DiseaseDisease
[ERCC4_HUMAN] Defects in ERCC4 are the cause of xeroderma pigmentosum complementation group F (XP-F) [MIM:278760]; also known as xeroderma pigmentosum VI (XP6). XP-F is an autosomal recessive disease characterized by hypersensitivity of the skin to sunlight followed by high incidence of skin cancer and frequent neurologic abnormalities.[1][2][3] Defects in ERCC4 are a cause of XFE progeroid syndrome (XFEPS) [MIM:610965]. This syndrome is illustrated by one patient who presented with dwarfism, cachexia and microcephaly.[4] [ERCC1_HUMAN] Defects in ERCC1 are the cause of cerebro-oculo-facio-skeletal syndrome type 4 (COFS4) [MIM:610758]. COFS is a degenerative autosomal recessive disorder of prenatal onset affecting the brain, eye and spinal cord. After birth, it leads to brain atrophy, hypoplasia of the corpus callosum, hypotonia, cataracts, microcornea, optic atrophy, progressive joint contractures and growth failure. Facial dysmorphism is a constant feature. Abnormalities of the skull, eyes, limbs, heart and kidney also occur.[5]
FunctionFunction
[ERCC4_HUMAN] Structure-specific DNA repair endonuclease responsible for the 5-prime incision during DNA repair. Involved in homologous recombination that assists in removing interstrand cross-link.[6] [ERCC1_HUMAN] Structure-specific DNA repair endonuclease responsible for the 5'-incision during DNA repair.
