Gene summary
This gene encodes a DNA-binding protein that is important in transcription-coupled excision repair. The encoded protein has ATP-stimulated ATPase activity, interacts with several transcription and excision repair proteins, and may promote complex formation at DNA repair sites. Mutations in this gene are associated with Cockayne syndrome type B and cerebrooculofacioskeletal syndrome 1. Alternative splicing occurs between a splice site from exon 5 of this gene to the 3' splice site upstream of the open reading frame (ORF) of the adjacent gene, piggyback-derived-3 (GeneID:267004), which activates the alternative polyadenylation site downstream of the piggyback-derived-3 ORF. The resulting transcripts encode a fusion protein that shares sequence with the product of each individual gene. [provided by RefSeq, Mar 2016]

The ERCC6 gene is located on chromosome 10 at 10q11.23 and encodes the Excision Repair 6, Chromatin Remodeling Factor protein, a DNA-binding protein that is important in transcription-coupled excision repair. ERCC6 was first reported in relation to autosomal recessive Cockayne spectrum with or without cerebrooculofacioskeletal syndrome in 1992 (Troelstra et al., PMID:1339317). Cockayne spectrum with or without cerebrooculofacioskeletal syndrome is characterized by growth failure at birth, with little or no postnatal neurologic development in addition to congenital cataracts or other structural anomalies of the eye, early postnatal contractures of the spine (kyphosis, scoliosis) and joints, and death usually occurring by age five years. This term lumps Cockayne syndrome type 2/B (CSB), cerebrooculofacioskeletal syndrome 1 (COFS syndrome), and De Sanctis-Cacchione syndrome into a spectrum of disease. Per criteria outlined by the ClinGen Lumping and Splitting Working Group, we found differences in inheritance pattern and/or phenotypic variability. Therefore, the following disease entities have been split into multiple disease entities, Cockayne spectrum with or without cerebrooculofacioskeletal syndrome (OMIM: 133540, 214150, 278800), premature ovarian failure 11 (OMIM: 616946), UV-sensitive syndrome 1 (OMIM: 600630), and susceptibilities to [lung] cancer (OMIM: 211980) and age-related macular degeneration (OMIM: 613761). 10 variants (nonsense, frameshift, canonical splice site, and inframe indel) that have been reported in 5 probands in 4 publications (Mallery et al., 1998, PMID:9443879; Colella et al., 1999, PMID:10196384; Laugel et al., 2010, PMID:19894250; Zhang et al., 2020, PMID:31558084) are included in this curation. More evidence is available in the literature, but the maximum score for genetic evidence (12 pts.) has been reached. The mechanism of pathogenicity is known to be LOF. This gene-disease relationship is also supported by experimental evidence (animal models, functional and phenotypic rescue, in vitro functional assays, and biochemical function) (Van der Horst et al., 1997, PMID: 9150142; Bradsher et al., 2002, PMID:12419226; Ciaffardini et al., 2014, PMID:24874740; Wang et al., 2014, PMID:25249633). One mouse model recapitulates some characteristic phenotypes of Cockayne syndrome, while both rRNA rates of transcription and UV-sensitivity are rescued in other models. It was also demonstrated that ERCC6 is essential to neuronal differentiation & neuritogenesis, consistent with delayed neurologic development seen in patients. Additionally, transcription-coupled repair of UV damage was shown to be inhibited by variants in ERCC6. In summary, ERCC6 is definitively associated with autosomal recessive Cockayne spectrum with or without cerebrooculofacioskeletal syndrome. This has been repeatedly demonstrated in both the research and clinical diagnostic settings, and has been upheld over time. This classification was approved by the ClinGen Syndromic Disorders Gene Curation Expert Panel on the meeting date July 15, 2022 (SOP Version 9).

Intervention: Audiologic/Otolaryngologic; Dermatologic; Gastrointestinal; Obstetric; Oncologic
Rationale: In Cockayne syndrome, periodic surveillance for manifestations affecting the audiologic, ophthalmologic, hepatic, and other systems can be beneficial; Metronidazole should be avoided due to concerns of hepatic failure; Some individuals with Xeroderma Pigmentosum-Cockayne Syndromecan have predisposition to skin cancer; Skin lesions can be treated (and possibly prevented in some cases) with a variety of methods, depending on the specific type of lesion; Sun/UV exposure (and other agents, such as tobacco smoke) should be avoided; Periodic surveillance for dermatologic manifestations can be beneficial; For Premature ovarian failure, genetic knowledge may be beneficial to allow interventions such as preserving eggs in women with premature ovarian insufficiency
Comments: Individuals with Cockayne syndrome without skin sensitivity have been described

- Function
- FUNCTION: Essential factor involved in transcription-coupled nucleotide excision repair which allows RNA polymerase II-blocking lesions to be rapidly removed from the transcribed strand of active genes. Upon DNA-binding, it locally modifies DNA conformation by wrapping the DNA around itself, thereby modifying the interface between stalled RNA polymerase II and DNA. It is required for transcription-coupled repair complex formation. It recruits the CSA complex (DCX(ERCC8) complex), nucleotide excision repair proteins and EP300 to the at sites of RNA polymerase II- blocking lesions. {ECO:0000269|PubMed:15548521, ECO:0000269|PubMed:16916636, ECO:0000269|PubMed:20541997, ECO:0000269|PubMed:22483866}.;
- Disease
- DISEASE: Cockayne syndrome B (CSB) [MIM:133540]: A rare disorder characterized by cutaneous sensitivity to sunlight, abnormal and slow growth, cachectic dwarfism, progeroid appearance, progressive pigmentary retinopathy and sensorineural deafness. There is delayed neural development and severe progressive neurologic degeneration resulting in mental retardation. Two clinical forms are recognized: in the classical form or Cockayne syndrome type 1, the symptoms are progressive and typically become apparent within the first few years or life; the less common Cockayne syndrome type 2 is characterized by more severe symptoms that manifest prenatally. Cockayne syndrome shows some overlap with certain forms of xeroderma pigmentosum. Unlike xeroderma pigmentosum, patients with Cockayne syndrome do not manifest increased freckling and other pigmentation abnormalities in the skin and have no significant increase in skin cancer. {ECO:0000269|PubMed:10447254, ECO:0000269|PubMed:19894250, ECO:0000269|PubMed:9443879}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Cerebro-oculo-facio-skeletal syndrome 1 (COFS1) [MIM:214150]: A disorder of prenatal onset characterized by microcephaly, congenital cataracts, facial dysmorphism, neurogenic arthrogryposis, growth failure and severe psychomotor retardation. COFS is considered to be part of the nucleotide-excision repair disorders spectrum that include also xeroderma pigmentosum, trichothiodystrophy and Cockayne syndrome. {ECO:0000269|PubMed:19894250}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: De Sanctis-Cacchione syndrome (DSC) [MIM:278800]: An autosomal recessive syndrome consisting of xeroderma pigmentosum associated with severe neurological and developmental involvement. In addition to the clinical signs of xeroderma pigmentosum, patients present with mental retardation, dwarfism, gonadal hypoplasia, microcephaly and various neurologic complications of early onset. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Macular degeneration, age-related, 5 (ARMD5) [MIM:613761]: A form of age-related macular degeneration, a multifactorial eye disease and the most common cause of irreversible vision loss in the developed world. In most patients, the disease is manifest as ophthalmoscopically visible yellowish accumulations of protein and lipid that lie beneath the retinal pigment epithelium and within an elastin-containing structure known as Bruch membrane. {ECO:0000269|PubMed:16754848}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: UV-sensitive syndrome 1 (UVSS1) [MIM:600630]: An autosomal recessive disorder characterized by cutaneous photosensitivity and mild freckling in the absence of neurological abnormalities or skin tumors. {ECO:0000269|PubMed:15486090}.
