Labcorp Genetics (formerly Invitae), Labcorp RCV005217919 SCV005858560 pathogenic Carney-Stratakis syndrome; Pheochromocytoma; Paragangliomas with sensorineural hearing loss; Cowden syndrome 3 2024-06-05 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Glu69Argfs*45) in the SDHD gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 91 amino acid(s) of the SDHD protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SDHD-related conditions. This variant disrupts a region of the SDHD protein in which other variant(s) (p.Ser132Glnfs*3) have been determined to be pathogenic (PMID: 18551016). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
