Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PVS1PS3PP5_Very_Strong

The NM_000122.2(ERCC3):c.1273C>T(p.Arg425*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,613,996 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV002513147: Published functions studies demonstrate a damaging effect resulting in defective DNA repair activity (Oh et al., 2006)" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. R425R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 20 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PS3

PS3 evidence extracted from ClinVar submissions: SCV002513147: Published functions studies demonstrate a damaging effect resulting in defective DNA repair activity (Oh et al., 2006);; SCV003631936: Functional studies show that this alteration leads to greatly reduced activity compared to wild type (Oh, 2006).

PP5

Variant 2-127286772-G-A is Pathogenic according to our data. Variant chr2-127286772-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 16585.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
