ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000755914 SCV000883569 pathogenic not provided 2017-05-31 criteria provided, single submitter clinical testing The CFTR c.1703delT, p.Leu568fs variant (also known as 1833delT) has been reported in patients with cystic fibrosis (SickKids CFTR database, CFTR2 databases), but the clinical symptoms were not described. It is listed in the ClinVar database (Variation ID: 53349) and the dbSNP variant database (rs397508274), but not observed in the general population databases (1000 Genomes Project, Exome Variant Server, Exome Aggregation Consortium). The variant introduces a frameshift, and is predicted to result in a truncated protein or an absent transcript. Based on the above information, the variant is classified as pathogenic, with uncertain clinical severity. References: CFTR2 database: SickKids CFTR database:
