Genes affected

XPC (HGNC:12816): (XPC complex subunit, DNA damage recognition and repair factor) The protein encoded by this gene is a key component of the XPC complex, which plays an important role in the early steps of global genome nucleotide excision repair (NER). The encoded protein is important for damage sensing and DNA binding, and shows a preference for single-stranded DNA. Mutations in this gene or some other NER components can result in Xeroderma pigmentosum, a rare autosomal recessive disorder characterized by increased sensitivity to sunlight with the development of carcinomas at an early age. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Aug 2017]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.84).

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000133 (102/765892) while in subpopulation MID AF = 0.0021 (6/2862). AF 95% confidence interval is 0.000913. There are 0 homozygotes in GnomAdExome4. There are 56 alleles in the male GnomAdExome4 subpopulation. Median coverage is 10. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
