Ambry Genetics | RCV003177580 | SCV003866426 | pathogenic | Hereditary cancer-predisposing syndrome | 2023-03-07 | criteria provided, single submitter | clinical testing | The c.466delT pathogenic mutation, located in coding exon 5 of the SDHA gene, results from a deletion of one nucleotide at nucleotide position 466, causing a translational frameshift with a predicted alternate stop codon (p.Y156Mfs*70). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. |

RCV003779566 | SCV004578443 | pathogenic | Mitochondrial complex II deficiency, nuclear type 1; Paragangliomas 5 | 2023-08-05 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 2452806). This variant has not been reported in the literature in individuals affected with SDHA-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr156Metfs*70) 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). |
