Invitae RCV000226464 SCV000288118 uncertain significance Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 2024-01-24 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 531 of the SDHA protein (p.Val531Met). This variant is present in population databases (rs371056571, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with SDHA-related conditions. ClinVar contains an entry for this variant (Variation ID: 212143). 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 SDHA protein function with a negative predictive value of 95%. 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 RCV000573905 SCV000674957 uncertain significance Hereditary cancer-predisposing syndrome 2023-06-23 criteria provided, single submitter clinical testing The p.V531M variant (also known as c.1591G>A), located in coding exon 12 of the SDHA gene, results from a G to A substitution at nucleotide position 1591. The valine at codon 531 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Myriad Genetics, Inc. RCV000410380 SCV004045351 uncertain significance Paragangliomas 5 2023-04-24 criteria provided, single submitter clinical testing This variant is classified as a variant of uncertain significance as there is insufficient evidence to determine its impact on protein function and/or cancer risk.
