Description

This variant is also known as c.713delT (p.Phe238fs). This premature translational stop signal has been observed in individual(s) with paraganglioma-pheochromocytoma syndromes (PMID: 16317055, 19454582, 22517554, 28490599). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change creates a premature translational stop signal (p.Phe238Serfs*10) in the SDHB gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 43 amino acid(s) of the SDHB protein. ClinVar contains an entry for this variant (Variation ID: 233795). For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the SDHB protein in which other variant(s) (p.Leu240Serfs*16) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing.
