Labcorp Genetics (formerly Invitae), Labcorp RCV002582325 SCV003492830 uncertain significance Syndromic X-linked intellectual disability 14 2022-10-07 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. 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 UPF3B protein function. This variant has not been reported in the literature in individuals affected with UPF3B-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 aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 155 of the UPF3B protein (p.Asp155Asn).
