RCV001116100 | SCV001274129 | uncertain significance | Xeroderma pigmentosum, group F | 2018-01-12 | 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. |

RCV001359252 | SCV001555115 | uncertain significance | Xeroderma pigmentosum, group F; Cockayne syndrome; Fanconi anemia complementation group Q | 2024-01-08 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 49 of the ERCC4 protein (p.Leu49Phe). This variant is present in population databases (rs552142099, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with ERCC4-related conditions. ClinVar contains an entry for this variant (Variation ID: 884829). 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 expected to disrupt ERCC4 protein function with a positive predictive value of 80%. 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. |

| Ambry Genetics | RCV004619518 | SCV005120836 | uncertain significance | Inborn genetic diseases | 2024-06-16 | criteria provided, single submitter | clinical testing | The c.145C>T (p.L49F) alteration is located in exon 1 (coding exon 1) of the ERCC4 gene. This alteration results from a C to T substitution at nucleotide position 145, causing the leucine (L) at amino acid position 49 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
