Labcorp Genetics (formerly Invitae), Labcorp RCV000806151 SCV000946133 uncertain significance Gorlin syndrome; Medulloblastoma 2023-11-21 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 427 of the SUFU protein (p.His427Arg). This variant is present in population databases (rs771305734, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SUFU-related conditions. ClinVar contains an entry for this variant (Variation ID: 650905). 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 SUFU protein function with a negative predictive value of 80%. 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.
Ambry Genetics RCV001010724 SCV001170961 benign Hereditary cancer-predisposing syndrome 2023-12-13 criteria provided, single submitter clinical testing This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
