Invitae | RCV001377218 | SCV001574492 | pathogenic | not provided | 2023-11-06 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 474 of the TGM1 protein (p.Pro474Ser). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individuals with congenital ichthyosis (PMID: 30578701, 31168818, 35412663). ClinVar contains an entry for this variant (Variation ID: 633790). 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 TGM1 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. |
