Labcorp Genetics (formerly Invitae), Labcorp RCV003798893 SCV004584010 uncertain significance Norman-Roberts syndrome; Familial temporal lobe epilepsy 7 2023-09-08 criteria provided, single submitter clinical testing 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. Studies have shown that this missense change alters RELN gene expression (PMID: 28419454). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RELN protein function. This variant has not been reported in the literature in individuals affected with RELN-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1742 of the RELN protein (p.Arg1742Trp).
