dbSNP rs121913024: ERCC2:p.Arg616Trp (chr19-45352802-G-A) – ACMG Classification: Pathogenic (20 pts)

Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS3PM2PM5PP3_StrongPP5_Very_Strong

The NM_000400.4(ERCC2):c.1846C>T(p.Arg616Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000626 in 1,613,504 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV001818743: Published functional studies demonstrate a damaging effect: R616W results in absent binding and transcriptional activity of TFIIH (PMID:12820975)" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R616Q) has been classified as Likely pathogenic.

Genes affected

ERCC2 (HGNC:3434): (ERCC excision repair 2, TFIIH core complex helicase subunit) The nucleotide excision repair pathway is a mechanism to repair damage to DNA. The protein encoded by this gene is involved in transcription-coupled nucleotide excision repair and is an integral member of the basal transcription factor BTF2/TFIIH complex. The gene product has ATP-dependent DNA helicase activity and belongs to the RAD3/XPD subfamily of helicases. Defects in this gene can result in three different disorders, the cancer-prone syndrome xeroderma pigmentosum complementation group D, trichothiodystrophy, and Cockayne syndrome. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

ACMG classification

Classification was made for transcript

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

PS3

PS3 evidence extracted from ClinVar submissions: SCV001818743: Published functional studies demonstrate a damaging effect: R616W results in absent binding and transcriptional activity of TFIIH (PMID: 12820975); SCV002125364: Experimental studies have shown that this missense change affects ERCC2 function (PMID: 25431422).; SCV002766025: At least one publication reports experimental evidence evaluating an impact on protein function (Dubaele_2003). The most pronounced variant effect results in abolishment of interaction with the p44 subunit of TFIIH and an inhibition of basal transcription activity.

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-45352801-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 997520.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.961

PP5

Variant 19-45352802-G-A is Pathogenic according to our data. Variant chr19-45352802-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 16788.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
