Description

This sequence change replaces histidine with proline at codon 102 of the SDHD protein (p.His102Pro). The histidine residue is highly conserved and there is a moderate physicochemical difference between histidine and proline. This variant is not present in population databases (ExAC no frequency). This variant has been observed in several individuals affected with clinical features of SDHD-related hereditary paraganglioma-pheochromocytoma syndrome (PMID: 19454582, Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant disrupts the p.His102 amino acid residue in SDHD. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10657297, 12811540, 19454582, 22025150, 22241717, Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
