RCV001389812 | SCV001591295 | pathogenic | Gastrointestinal stromal tumor; Paragangliomas 4; Pheochromocytoma | 2024-11-02 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Tyr61*) in the SDHB gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SDHB are known to be pathogenic (PMID: 19454582, 19802898). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with paraganglioma (PMID: 20418362). ClinVar contains an entry for this variant (Variation ID: 438412). For these reasons, this variant has been classified as Pathogenic. |

| Ambry Genetics | RCV002413384 | SCV002717032 | pathogenic | Hereditary cancer-predisposing syndrome | 2024-12-18 | criteria provided, single submitter | clinical testing | The p.Y61* pathogenic mutation (also known as c.183T>G), located in coding exon 2 of the SDHB gene, results from a T to G substitution at nucleotide position 183. This changes the amino acid from a tyrosine to a stop codon within coding exon 2. This alteration has been detected in multiple individuals diagnosed with a paraganglioma or pheochromocytoma (Lodish MB et al. Endocr Relat Cancer. 2010 Sep;17:581-8; Jochmanova I et al. J Cancer Res Clin Oncol. 2017 Aug;143:1421-1435; Ambry internal data). 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. |
