RCV003807732 | SCV004591984 | pathogenic | Axenfeld-Rieger syndrome type 1; Anterior segment dysgenesis 4 | 2023-01-30 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Ala73 amino acid residue in PITX2. Other variant(s) that disrupt this residue have been observed in individuals with PITX2-related conditions (PMID: 30457409; Invitae), which suggests that this may be a clinically significant amino acid residue. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This missense change has been observed in individual(s) with clinical features of Axenfeld-Rieger syndrome (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 73 of the PITX2 protein (p.Ala73Pro). |
