The following ACMG criteria were applied in classifying this variant: PS1,PM2,PP2,PP3. This variant was detected in homozygous state.
Labcorp Genetics (formerly Invitae), Labcorp RCV001198281 SCV003461865 pathogenic Leber congenital amaurosis 13 2023-10-25 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 126 of the RDH12 protein (p.Ala126Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with inherited retinal dystrophy (PMID: 28559085). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 931585). 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 RDH12 protein function with a positive predictive value of 80%. This variant disrupts the p.Ala126 amino acid residue in RDH12. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 19140180, 30134391). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
