Labcorp Genetics (formerly Invitae), Labcorp RCV001894510 SCV002123045 uncertain significance Familial aplasia of the vermis; Meckel-Gruber syndrome 2021-09-24 criteria provided, single submitter clinical testing This sequence change replaces leucine with phenylalanine at codon 152 of the TMEM67 protein (p.Leu152Phe). The leucine residue is moderately conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with TMEM67-related conditions. 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 TMEM67 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.
