Labcorp Genetics (formerly Invitae), Labcorp RCV001047882 SCV001211864 pathogenic Axenfeld-Rieger syndrome type 1; Anterior segment dysgenesis 4 2019-01-11 criteria provided, single submitter clinical testing This sequence change results in a premature translational stop signal in the PITX2 gene (p.Ile72Serfs*83). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 897 amino acids of the PITX2 protein. For these reasons, this variant has been classified as Pathogenic. This variant disrupts the C-terminus of the PITX2 protein. Other variant(s) that disrupt this region (p.Trp133*) have been determined to be pathogenic (PMID: 8944018, 16498627, 22569110). This suggests that variants that disrupt this region of the protein are likely to be causative of disease. This variant has not been reported in the literature in individuals with PITX2-related conditions. This variant is not present in population databases (ExAC no frequency).
