Genes affected

ERCC4 (HGNC:3436): (ERCC excision repair 4, endonuclease catalytic subunit) The protein encoded by this gene forms a complex with ERCC1 and is involved in the 5' incision made during nucleotide excision repair. This complex is a structure specific DNA repair endonuclease that interacts with EME1. Defects in this gene are a cause of xeroderma pigmentosum complementation group F (XP-F), or xeroderma pigmentosum VI (XP6).[provided by RefSeq, Mar 2009]

The ERCC4 p.Gly912Arg variant was not identified in the literature nor was it identified in Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs150077735) and ClinVar (classified as likely benign by Invitae). The variant was identified in control databases in 58 of 264586 chromosomes (1 homozygous) at a frequency of 0.0002192 (Genome Aggregation Database March 6, 2019, v2.1.1, non-cancer). The variant was observed in the following populations: East Asian in 57 of 19170 chromosomes (freq: 0.002973) and Latino in 1 of 35058 chromosomes (freq: 0.000029), but was not observed in the African, Ashkenazi Jewish, European (Finnish), European (non-Finnish), Other, or South Asian populations. The p.Gly912 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
