Ambry Genetics RCV000221764 SCV000274559 pathogenic Hereditary cancer-predisposing syndrome 2024-01-10 criteria provided, single submitter clinical testing The p.S384* pathogenic mutation (also known as c.1151C>G), located in coding exon 9 of the SDHA gene, results from a C to G substitution at nucleotide position 1151. This changes the amino acid from a serine to a stop codon within coding exon 9. This mutation was previously identified in a homozygous state in a gastrointetstinal stromal tumor (GIST) and was subsequently confirmed to be heterozygous in this individual's germline (Pantaleo MA, J. Natl. Cancer Inst. 2011 Jun; 103(12):983-7). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
Labcorp Genetics (formerly Invitae), Labcorp RCV000810033 SCV000950219 pathogenic Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 2024-01-05 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Ser384*) 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). This variant is present in population databases (rs151170408, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with gastrointestinal stromal tumor (PMID: 21505157). ClinVar contains an entry for this variant (Variation ID: 230877). For these reasons, this variant has been classified as Pathogenic.
