hMSH2; MutS protein homolog 2; Mismatch repair gene Msh2

DNA mismatch repair MutS family

NA

Forms two different heterodimers: MutS alpha (MSH2-MSH6 heterodimer) and MutS beta (MSH2-MSH3 heterodimer) which binds to DNA mismatches thereby initiating DNA repair. When bound, heterodimers bend the DNA helix and shields approximately 20 base pairs. MutS alpha recognizes single base mismatches and dinucleotide insertion-deletion loops (IDL) in the DNA. MutS beta recognizes larger insertion-deletion loops up to 13 nucleotides long. After mismatch binding, MutS alpha or beta forms a ternary complex with the MutL alpha heterodimer, which is thought to be responsible for directing the downstream MMR events, including strand discrimination, excision, and resynthesis. Recruits DNA helicase MCM9 to chromatin which unwinds the mismatch containg DNA strand. ATP binding and hydrolysis play a pivotal role in mismatch repair functions. The ATPase activity associated with MutS alpha regulates binding similar to a molecular switch: mismatched DNA provokes ADP-->ATP exchange, resulting in a discernible conformational transition that converts MutS alpha into a sliding clamp capable of hydrolysis-independent diffusion along the DNA backbone. This transition is crucial for mismatch repair. MutS alpha may also play a role in DNA homologous recombination repair. In melanocytes may modulate both UV-B-induced cell cycle regulation and apoptosis. Component of the post-replicative DNA mismatch repair system (MMR).

Lynch syndrome 1 (LYNCH1) [MIM:120435]: A form of Lynch syndrome, an autosomal dominant disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early-onset colorectal carcinoma (CRC) and extra-colonic tumors of the gastrointestinal, urological and female reproductive tracts. Lynch syndrome is reported to be the most common form of inherited colorectal cancer in the Western world. Clinically, it is often divided into two subgroups. Type I is characterized by hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II is characterized by increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical Lynch syndrome is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes. The term 'suspected Lynch syndrome' or 'incomplete Lynch syndrome' can be used to describe families who do not or only partially fulfill the Amsterdam criteria, but in whom a genetic basis for colon cancer is strongly suspected. {ECO:0000269|PubMed:10375096, ECO:0000269|PubMed:10386556, ECO:0000269|PubMed:10528862, ECO:0000269|PubMed:10573010, ECO:0000269|PubMed:10612836, ECO:0000269|PubMed:10777691, ECO:0000269|PubMed:10829038, ECO:0000269|PubMed:11726306, ECO:0000269|PubMed:11870161, ECO:0000269|PubMed:11920458, ECO:0000269|PubMed:12112654, ECO:0000269|PubMed:12124176, ECO:0000269|PubMed:12132870, ECO:0000269|PubMed:12200596, ECO:0000269|PubMed:12362047, ECO:0000269|PubMed:12373605, ECO:0000269|PubMed:12655564, ECO:0000269|PubMed:12655568, ECO:0000269|PubMed:12658575, ECO:0000269|PubMed:14635101, ECO:0000269|PubMed:15046096, ECO:0000269|PubMed:15300854, ECO:0000269|PubMed:15342696, ECO:0000269|PubMed:15365995, ECO:0000269|PubMed:15613555, ECO:0000269|PubMed:15870828, ECO:0000269|PubMed:15896463, ECO:0000269|PubMed:15991316, ECO:0000269|PubMed:15996210, ECO:0000269|PubMed:16451135, ECO:0000269|PubMed:17101317, ECO:0000269|PubMed:17128465, ECO:0000269|PubMed:18561205, ECO:0000269|PubMed:18625694, ECO:0000269|PubMed:18781619, ECO:0000269|PubMed:18822302, ECO:0000269|PubMed:18951462, ECO:0000269|PubMed:21120944, ECO:0000269|PubMed:22102614, ECO:0000269|PubMed:22371642, ECO:0000269|PubMed:7874129, ECO:0000269|PubMed:8261515, ECO:0000269|PubMed:8700523, ECO:0000269|PubMed:8797773, ECO:0000269|PubMed:8872463, ECO:0000269|PubMed:9048925, ECO:0000269|PubMed:9240418, ECO:0000269|PubMed:9298827, ECO:0000269|PubMed:9311737, ECO:0000269|PubMed:9419403, ECO:0000269|PubMed:9559627, ECO:0000269|PubMed:9621522, ECO:0000269|PubMed:9718327, ECO:0000269|PubMed:9889267}.

CYPIB1

Cytochrome P450 family

Paired donor oxygen oxidoreductase

In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, retinoid and xenobiotics. Preferentially oxidizes 17beta-estradiol to the carcinogenic 4-hydroxy derivative, and a variety of procarcinogenic compounds to their activated forms, including polycyclic aromatic hydrocarbons. Promotes angiogenesis by removing cellular oxygenation products, thereby decreasing oxidative stress, release of antiangiogenic factor THBS2, then allowing endothelial cells migration, cell adhesion and capillary morphogenesis. These changes are concommitant with the endothelial nitric oxide synthase activity and nitric oxide synthesis. Plays an important role in the regulation of perivascular cell proliferation, migration, and survival through modulation of the intracellular oxidative state and NF-kappa-B expression and/or activity, during angiogenesis. Contributes to oxidative homeostasis and ultrastructural organization and function of trabecular meshwork tissue through modulation of POSTN expression. Cytochromes P450 are a group of heme-thiolate monooxygenases.

Anterior segment dysgenesis 6 (ASGD6) [MIM:617315]: A form of anterior segment dysgenesis, a group of defects affecting anterior structures of the eye including cornea, iris, lens, trabecular meshwork, and Schlemm canal. Anterior segment dysgeneses result from abnormal migration or differentiation of the neural crest derived mesenchymal cells that give rise to components of the anterior chamber during eye development. Different anterior segment anomalies may exist alone or in combination, including iris hypoplasia, enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface. Clinical conditions falling within the phenotypic spectrum of anterior segment dysgeneses include aniridia, Axenfeld anomaly, Reiger anomaly/syndrome, Peters anomaly, and iridogoniodysgenesis. ASGD6 patients predominantly manifest Peters anomaly. Peters anomaly consists of corneal leukoma, defects in the posterior structures of the cornea such as absence of the posterior corneal stroma and Descemet membrane, and a variable degree of iridocorneal and/or keratolenticular adhesions. Over 50% of patients develop glaucoma in childhood. {ECO:0000269|PubMed:11403040}. The disease is caused by variants affecting the gene represented in this entry.; DISEASE: Glaucoma 3, primary congenital, A (GLC3A) [MIM:231300]: An autosomal recessive form of primary congenital glaucoma (PCG).

It results from developmental defects of the trabecular meshwork and anterior chamber angle of the eye that prevent adequate drainage of aqueous humor. {ECO:0000269|PubMed:10227395, ECO:0000269|PubMed:10655546, ECO:0000269|PubMed:11184479, ECO:0000269|PubMed:11527932, ECO:0000269|PubMed:11774072, ECO:0000269|PubMed:11980847, ECO:0000269|PubMed:12036985, ECO:0000269|PubMed:12525557, ECO:0000269|PubMed:14635112, ECO:0000269|PubMed:14640114, ECO:0000269|PubMed:15255109, ECO:0000269|PubMed:15342693, ECO:0000269|PubMed:15475877, ECO:0000269|PubMed:16490498, ECO:0000269|PubMed:16688110, ECO:0000269|PubMed:16735994, ECO:0000269|PubMed:16862072, ECO:0000269|PubMed:18470941, ECO:0000269|PubMed:9463332, ECO:0000269|PubMed:9497261}. The disease is caused by variants affecting distinct genetic loci, including the gene represented in this entry.; DISEASE: Glaucoma 1, open angle, A (GLC1A) [MIM:137750]: A form of primary open angle glaucoma (POAG). POAG is characterized by a specific pattern of optic nerve and visual field defects. The angle of the anterior chamber of the eye is open, and usually the intraocular pressure is increased. However, glaucoma can occur at any intraocular pressure. The disease is generally asymptomatic until the late stages, by which time significant and irreversible optic nerve damage has already taken place. {ECO:0000269|PubMed:11774072}. The gene represented in this entry acts as a disease modifier. Digenic mutations in CYP1B1 and MYOC have been found in a family segregating both primary adult-onset and juvenile forms of open angle glaucoma (PubMed:11774072). All affected family members with mutations in both MYOC and CYP1B1 had juvenile glaucoma, whereas those with only the MYOC mutation had the adult-onset form (PubMed:11774072). {ECO:0000269|PubMed:11774072}.

Activation by various effectors including growth factor receptors or active CDC42 and RAC1 results in a conformational change and a subsequent autophosphorylation on several serine and/or threonine residues. Phosphorylates and inactivates the protein phosphatase SSH1, leading to increased inhibitory phosphorylation of the actin binding/depolymerizing factor cofilin. Decreased cofilin activity may lead to stabilization of actin filaments. Phosphorylates LIMK1, a kinase that also inhibits the activity of cofilin. Phosphorylates integrin beta5/ITGB5 and thus regulates cell motility. Phosphorylates ARHGEF2 and activates the downstream target RHOA that plays a role in the regulation of assembly of focal adhesions and actin stress fibers. Stimulates cell survival by phosphorylating the BCL2 antagonist of cell death BAD. Alternatively, inhibits apoptosis by preventing caspase-8 binding to death domain receptors in a kinase independent manner. Plays a role in cell-cycle progression by controlling levels of the cell-cycle regulatory protein CDKN1A and by phosphorylating RAN. Serine/threonine protein kinase that plays a role in a variety of different signaling pathways including cytoskeleton regulation, cell migration, growth, proliferation or cell survival.

Metachromatic leukodystrophy (MLD) [MIM:250100]: An autosomal recessive disease caused by abnormal intralysosomal accumulation of cerebroside-3-sulfate in central and peripheral nervous systems, as well as other organs. MLD is clinically characterized by leukodystrophy, progressive demyelination and a variety of neurological symptoms, including gait disturbances, ataxias, optical atrophy, dementia, seizures, and spastic tetraparesis. Decreased arylsulfatase A activity is detected in urine, leukocytes, and fibroblasts of affected individuals. Several forms of the disease can be distinguished according to the age at onset and disease severity: late infantile, juvenile and adult forms, partial cerebroside sulfate deficiency, and pseudoarylsulfatase A deficiency. Individuals with pseudoarylsulfatase A deficiency have low arylsulfatase A activity but lack neurological manifestations and are apparently healthy. {ECO:0000269|PubMed:10220151, ECO:0000269|PubMed:10381328, ECO:0000269|PubMed:10477432, ECO:0000269|PubMed:10533072, ECO:0000269|PubMed:10751093, ECO:0000269|PubMed:11020646, ECO:0000269|PubMed:11061266, ECO:0000269|PubMed:11456299, ECO:0000269|PubMed:11941485, ECO:0000269|PubMed:12503099, ECO:0000269|PubMed:12788103, ECO:0000269|PubMed:1353340, ECO:0000269|PubMed:14517960, ECO:0000269|PubMed:14680985, ECO:0000269|PubMed:15026521, ECO:0000269|PubMed:15326627, ECO:0000269|PubMed:15710861, ECO:0000269|PubMed:1670590, ECO:0000269|PubMed:1673291, ECO:0000269|PubMed:1678251, ECO:0000269|PubMed:18693274, ECO:0000269|PubMed:19606494, ECO:0000269|PubMed:20339381, ECO:0000269|PubMed:21265945, ECO:0000269|PubMed:2574462, ECO:0000269|PubMed:7581401, ECO:0000269|PubMed:7825603, ECO:0000269|PubMed:7860068, ECO:0000269|PubMed:7902317, ECO:0000269|PubMed:7906588, ECO:0000269|PubMed:7909527, ECO:0000269|PubMed:8095918, ECO:0000269|PubMed:8101038, ECO:0000269|PubMed:8101083, ECO:0000269|PubMed:8104633, ECO:0000269|PubMed:8891236, ECO:0000269|PubMed:9090526, ECO:0000269|PubMed:9272717, ECO:0000269|PubMed:9452102, ECO:0000269|PubMed:9490297, ECO:0000269|PubMed:9600244, ECO:0000269|PubMed:9819708}.

Kinase

Binding of extracellular ligands such as growth factors, cytokines and hormones to their cell-surface receptors activates RAS and this initiates RAF1 activation. RAF1 then further activates the dual-specificity protein kinases MAP2K1/MEK1 and MAP2K2/MEK2. Both MAP2K1/MEK1 and MAP2K2/MEK2 function specifically in the MAPK/ERK cascade, and catalyze the concomitant phosphorylation of a threonine and a tyrosine residue in a Thr-Glu-Tyr sequence located in the extracellular signal-regulated kinases MAPK3/ERK1 and MAPK1/ERK2, leading to their activation and further transduction of the signal within the MAPK/ERK cascade. Depending on the cellular context, this pathway mediates diverse biological functions such as cell growth, adhesion, survival and differentiation, predominantly through the regulation of transcription, metabolism and cytoskeletal rearrangements. One target of the MAPK/ERK cascade is peroxisome proliferator-activated receptor gamma (PPARG), a nuclear receptor that promotes differentiation and apoptosis. MAP2K1/MEK1 has been shown to export PPARG from the nucleus. The MAPK/ERK cascade is also involved in the regulation of endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC), as well as in the fragmentation of the Golgi apparatus during mitosis. Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway.

Cardiofaciocutaneous syndrome 3 (CFC3) [MIM:615279]: A form of cardiofaciocutaneous syndrome, a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects and intellectual disability.

Class V-like SAM-binding methyltransferase superfamily, Histone-lysine methyltransferase family, Suvar4-20 subfamily

NA

Histone methyltransferase that specifically methylates monomethylated 'Lys-20' (H4K20me1) and dimethylated 'Lys-20' (H4K20me2) of histone H4 to produce respectively dimethylated 'Lys-20' (H4K20me2) and trimethylated 'Lys-20' (H4K20me3) and thus regulates transcription and maintenance of genome integrity. In vitro also methylates unmodified 'Lys-20' (H4K20me0) of histone H4 and nucleosomes. H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression. Mainly functions in pericentric heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin in these regions. KMT5C is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2) (By similarity). Facilitates TP53BP1 foci formation upon DNA damage and proficient non-homologous end-joining (NHEJ)-directed DNA repair by catalyzing the di- and trimethylation of 'Lys-20' of histone H4. May play a role in class switch reconbination by catalyzing the di- and trimethylation of 'Lys-20' of histone H4 (By similarity).

Brachydactyly A2 (BDA2) [MIM:112600]: A form of brachydactyly. Brachydactyly defines a group of inherited malformations characterized by shortening of the digits due to abnormal development of the phalanges and/or the metacarpals. In brachydactyly type A2 shortening of the middle phalanges is confined to the index finger and the second toe, all other digits being more or less normal. Because of a rhomboid or triangular shape of the affected middle phalanx, the end of the second finger usually deviates radially. {ECO:0000269|PubMed:19327734, ECO:0000269|PubMed:21357617}. The gene represented in this entry is involved in disease pathogenesis. Duplications of a cis-regulatory element located approximately 110 kb downstream of BMP2 have been found in BDA2 families. They likely cause altered BMP2 expression with pathological consequences. {ECO:0000269|PubMed:19327734, ECO:0000269|PubMed:21357617}.; DISEASE: Short stature, facial dysmorphism, and skeletal anomalies with or without cardiac anomalies 1 (SSFSC1) [MIM:617877]: An autosomal dominant disorder characterized by short stature, facial dysmorphism, skeletal anomalies, and variable cardiac defects.
