Labcorp Genetics (formerly Invitae), Labcorp RCV001039513 SCV001203045 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome 2024-01-22 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 623 of the RPGRIP1L protein (p.Ala623Pro). This variant is present in population databases (rs776297522, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with RPGRIP1L-related conditions. ClinVar contains an entry for this variant (Variation ID: 838047). 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 not expected to disrupt RPGRIP1L protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

PreventionGenetics, part of Exact Sciences RCV004733113 SCV005344560 uncertain significance RPGRIP1L-related disorder 2024-03-18 no assertion criteria provided clinical testing The RPGRIP1L c.1867G>C variant is predicted to result in the amino acid substitution p.Ala623Pro. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.048% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
