Labcorp Genetics (formerly Invitae), Labcorp RCV002601801 SCV002956897 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome 2021-09-24 criteria provided, single submitter clinical testing This sequence change replaces arginine with leucine at codon 161 of the RPGRIP1L protein (p.Arg161Leu). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and leucine. This variant is present in population databases (rs74957591, ExAC 0.003%). This variant has not been reported in the literature in individuals with RPGRIP1L-related conditions. 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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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 RCV004733520 SCV005363265 uncertain significance RPGRIP1L-related disorder 2024-03-07 no assertion criteria provided clinical testing The RPGRIP1L c.482G>T variant is predicted to result in the amino acid substitution p.Arg161Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0035% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
