RCV000351813 | SCV000394875 | uncertain significance | Xeroderma pigmentosum, group F | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |
| Invitae | RCV001049483 | SCV001213532 | uncertain significance | Xeroderma pigmentosum, group F; Cockayne syndrome; Fanconi anemia complementation group Q | 2023-05-31 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ERCC4 protein function. ClinVar contains an entry for this variant (Variation ID: 317816). This missense change has been observed in individual(s) with serous cystadenoma of the pancreas (PMID: 28767289). This variant is present in population databases (rs765454246, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 576 of the ERCC4 protein (p.Arg576Ser). |
| Baylor Genetics | RCV001292598 | SCV001481180 | uncertain significance | Fanconi anemia complementation group Q | 2020-06-05 | criteria provided, single submitter | clinical testing | This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. |

RCV000351813 | SCV002526100 | uncertain significance | Xeroderma pigmentosum, group F | 2022-03-10 | criteria provided, single submitter | clinical testing | The ERCC4 c.1728A>T (p.Arg576Ser) missense change has a maximum subpopulation frequency of 0.014% in gnomAD v2.1.1 ( https://gnomad.broadinstitute.org/variant/16-14029517-A-T ). Six of seven in silico tools predict a benign effect of this variant on protein function (BP4), but to our knowledge these predictions have not been confirmed by functional assays. This variant has been reported in an individual with serous cystadenoma (PMID: 28767289). The variant has been identified in 1 of 1358 control individuals collected as part of non-cancer studies (PMID: 29641532). To our knowledge, this variant has not been reported in individuals with Fanconi anemia or Xeroderma pigmentosum. In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: BP4. |
