Description

The SDHA c.841A>G variant is predicted to result in the amino acid substitution p.Thr281Ala. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0040% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/5-231061-A-G) and has been interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/548821/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
