Illumina Clinical Services Laboratory,Illumina RCV000778818 SCV000915205 uncertain significance Cystic fibrosis 2017-04-28 criteria provided, single submitter clinical testing The CFTR c.1826A>T (p.His609Leu) variant is a missense variant that has been reported in a compound heterozygous state with an intronic variant in one individual with congenital bilateral absence of the vas deferens (CBAVD) (Steiner et al. 2011). The p.His609Leu variant was absent from 319 controls. This variant is not found in the 1000 Genomes Project, the Exome Sequencing Project, or the Exome Aggregation Consortium despite being found in a region of good sequencing coverage. Therefore, it is presumed to be rare. Based on the limited evidence, the p.His609Leu variant is classified as a variant of unknown significance but suspicious for pathogenicity for CFTR-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
