Genes affected
ERCC3 (HGNC:3435): (ERCC excision repair 3, TFIIH core complex helicase subunit) This gene encodes an ATP-dependent DNA helicase that functions in nucleotide excision repair. The encoded protein is a subunit of basal transcription factor 2 (TFIIH) and, therefore, also functions in class II transcription. Mutations in this gene are associated with Xeroderma pigmentosum B, Cockayne's syndrome, and trichothiodystrophy. Alternative splicing results in multiple transcript variants.

Variant summary: ERCC3 c.1960G>A (p.Glu654Lys) results in a conservative amino acid change located in the Helicase, C-terminal domain (IPR001650) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00046 in 251470 control chromosomes (gnomAD), predominantly at a frequency of 0.0037 within the South Asian subpopulation in the gnomAD database, including 1 homozygote. The observed variant frequency within South Asian control individuals in the gnomAD database is approximately 33 fold of the estimated maximal expected allele frequency for a pathogenic variant in ERCC3 causing Xeroderma Pigmentosum phenotype (0.00011), strongly suggesting that the variant is a benign polymorphism found primarily in populations of South Asian origin. One ClinVar submitter has assessed the variant since 2014: the variant was classified as likely benign. Based on the evidence outlined above, the variant was classified as benign. -
