Invitae RCV002241158 SCV001395934 pathogenic Carney-Stratakis syndrome; Pheochromocytoma; Paragangliomas with sensorineural hearing loss; Cowden syndrome 3 2023-02-15 criteria provided, single submitter clinical testing This variant disrupts a region of the SDHD protein in which other variant(s) (p.Gly138Arg) have been determined to be pathogenic (PMID: 29875428, 31492822; 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. This sequence change creates a premature translational stop signal (p.Leu129Phefs*63) in the SDHD gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 31 amino acid(s) of the SDHD protein. This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with paraganglioma (Invitae). ClinVar contains an entry for this variant (Variation ID: 951786). For these reasons, this variant has been classified as Pathogenic.
