Genes affected

SDHD (HGNC:10683): (succinate dehydrogenase complex subunit D) This gene encodes a member of complex II of the respiratory chain, which is responsible for the oxidation of succinate. The encoded protein is one of two integral membrane proteins anchoring the complex to the matrix side of the mitochondrial inner membrane. Mutations in this gene are associated with the formation of tumors, including hereditary paraganglioma. Transmission of disease occurs almost exclusively through the paternal allele, suggesting that this locus may be maternally imprinted. There are pseudogenes for this gene on chromosomes 1, 2, 3, 7, and 18. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2013]

DNA sequence analysis of the SDHD gene demonstrated a sequence change, c.269C>T, in exon 3 that results in an amino acid change, p.Ala90Val. This sequence change has been described gnomAD with a frequency of 0.091% in the South Asian sub-population (dbSNP rs200255724). The p.Ala90Val change affects a poorly conserved amino acid residue located in a domain of the SDHD protein that is known to be functional. The p.Ala90Val substitution appears to be tolerated using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change does not appear to have been previously described in patients with SDHD-related disorders. Due to the lack of sufficient evidences, the clinical significance of the p.Ala90Val change remains unknown at this time. -

This alteration is classified as likely 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. -
