ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000579152 SCV000883575 pathogenic not provided 2017-10-04 criteria provided, single submitter clinical testing The CFTR c.3472C>T; p.Arg1158Ter variant is reported in the medical literature in individuals with cystic fibrosis and related disorders (Amato 2012, Frossard 2000, Ooi 2012, Sosnay 2013). The variant is listed in the ClinVar database (Variation ID: 7144), in the dbSNP variant database (rs79850223), and in the Genome Aggregation Database with a low population frequency (8/245236 alleles). This variant introduces a premature termination codon and is predicted to result in a truncated protein or mRNA subject to non-sense mediated decay. Considering available information, this variant is classified as severely pathogenic. References: Amato F et al. Extensive molecular analysis of patients bearing CFTR-related disorders.

GeneDx RCV000579152 SCV000680709 pathogenic not provided 2017-06-16 criteria provided, single submitter clinical testing The R1158X variant in the CFTR gene has been reported previously in association with cystic fibrosis (Ronchetto et al., 1992; Frossard et al., 2000; Ooi et al., 2012; Sosnay et al., 2013). This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R1158X variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). We interpret R1158X as a pathogenic variant.
Integrated Genetics/Laboratory Corporation of America RCV000007564 SCV000696972 pathogenic Cystic fibrosis 2016-09-28 criteria provided, single submitter clinical testing Variant summary: The CFTR c.3472C>T (p.Arg1158X) variant results in a premature termination codon, predicted to cause a truncated or absent CFTR protein due to nonsense mediated decay, which are commonly known mechanisms in CF or CFTR-related diseases. Truncations downstream of this position have been classified as pathogenic by our laboratory (e.g. p.Arg1162X, p.Gln1382X, p.Ser1455X, etc.). This variant was found in 5/120064 control chromosomes at a frequency of 0.0000416, which does not exceed the estimated maximal expected allele frequency of a pathogenic CFTR variant (0.0129603). This variant has been reported in many affected individuals with CF and CF-RDs (Amato_2012, Sosnay_2013). Multiple clinical diagnostic laboratories/reputable databases have classified this variant as pathogenic. Taken together, this variant is classified as Pathogenic.
