Neuberg Centre For Genomic Medicine, NCGM RCV001705707 SCV005042907 likely pathogenic Cystic fibrosis criteria provided, single submitter clinical testing The missense c.598T>Ap.Phe200Ile variant in CFTR gene has been reported previously in homozygous or compound heterozygous state in individuals affected with Cystic fibrosis Dorfman et al., 2010. This variant is reported with the allele frequency of 0.0004% in the gnomAD Exomes and novel in 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain Significance / Likely Pathogenic / Pathogenic. However, study of the variant in multiple affected individuals and its functional impact on the protein is required to determine the pathogenicity of the variant. The amino acid Phe at position 200 is changed to a Ile changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Phe200Ile in CFTR is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. This variant is located in a mutational hot spot. The variant is predicted as damaging by SIFT. For these reasons, this variant has been classified as Likely Pathogenic.
