Labcorp Genetics (formerly Invitae), Labcorp RCV001054418 SCV001218731 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome 2022-10-24 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 161 of the RPGRIP1L protein (p.Arg161Cys). This variant is present in population databases (rs374860980, gnomAD 0.06%). 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: 850282). 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. 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.
GeneDx RCV002508286 SCV002818010 uncertain significance not provided 2024-07-01 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge

PreventionGenetics, part of Exact Sciences RCV004545032 SCV004781717 uncertain significance RPGRIP1L-related disorder 2024-03-27 no assertion criteria provided clinical testing The RPGRIP1L c.481C>T variant is predicted to result in the amino acid substitution p.Arg161Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.052% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
