RCV002574134 | SCV002935072 | pathogenic | Familial aplasia of the vermis | 2023-10-15 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 527 of the AHI1 protein (p.Pro527Leu). This variant is present in population databases (rs750264231, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of Joubert syndrome and/or retinitis pigmentosa (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 1898879). 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 AHI1 protein function. For these reasons, this variant has been classified as Pathogenic. |
