Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP3_StrongPP5_Moderate
The NM_000526.5(KRT14):c.357G>A(p.Met119Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M119T) has been classified as Pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 23, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Met119 amino acid residue in KRT14. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11710919). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 KRT14 protein function. ClinVar contains an entry for this variant (Variation ID: 14620). This missense change has been observed in individual(s) with autosomal dominant epidermolysis bullosa simplex (PMID: 7561171, 23746086). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 119 of the KRT14 protein (p.Met119Ile). - |
