Specifically, we validated the assay for the HFE C282Y variant, the primary cause of type 1 hemochromatosis. The assay was tested on genomic DNA and DNA resulting from whole-genome amplification, achieving &gt;99% accuracy, sensitivity, precision, and specificity. These results also suggest the possibility for extending the PCR-RFLP approach to cover a broader range of conditions, such as spinal muscular atrophy, to benefit more patients currently ineligible for testing at PGT laboratories.</div></div>","PeriodicalId":73012,"journal":{"name":"F&S science","volume":"6 2","pages":"Pages 195-201"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142883745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
