Description

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 654714). This variant has not been reported in the literature in individuals affected with SDHA-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu10Cysfs*2) in the SDHA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SDHA are known to be pathogenic (PMID: 22974104, 24781757).
