Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000029545 SCV000052197 pathogenic Cystic fibrosis 2021-03-04 criteria provided, single submitter clinical testing Variant summary: CFTR c.825C>G (p.Tyr275X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 249138 control chromosomes. c.825C>G has been reported in the literature in individuals affected with Classic Cystic Fibrosis (Bernardino 2000, McGinniss 2005, Claustres 2017, Dankert-Roelse 2018). These data indicate that the variant is likely to be associated with disease. At least one publication reported experimental evidence, evaluating the basal and drug induced read-through levels of this premature termination codon, and reported less than 0.5% basal read-through activities and low levels of drug induced responses (Pranke 2018). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
