Invitae RCV001299452 SCV001488539 uncertain significance Carney-Stratakis syndrome; Pheochromocytoma; Paragangliomas 1; Cowden syndrome 3 2020-09-26 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with asparagine at codon 118 of the SDHD protein (p.Asp118Asn). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SDHD-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 SDHD 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.
