| Invitae | RCV000056550 | SCV004294171 | likely pathogenic | not provided | 2023-12-30 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 438 of the KRT5 protein (p.Ala438Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of epidermolysis bullosa simplex (PMID: 12655565; Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 66205). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on KRT5 protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
