Ambry Genetics | RCV001020477 | SCV001181963 | pathogenic | Hereditary cancer-predisposing syndrome | 2019-05-15 | criteria provided, single submitter | clinical testing | The c.3508delT pathogenic mutation, located in coding exon 17 of the BLM gene, results from a deletion of one nucleotide at nucleotide position 3508, causing a translational frameshift with a predicted alternate stop codon (p.Y1170Mfs*2). 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. |

RCV000674492 | SCV001591552 | pathogenic | Bloom syndrome | 2023-09-08 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Tyr1170Metfs*2) in the BLM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BLM are known to be pathogenic (PMID: 17407155). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 558254). This variant has not been reported in the literature in individuals affected with BLM-related conditions. This variant is not present in population databases (gnomAD no frequency). |
