Quest Diagnostics Nichols Institute San Juan Capistrano RCV000985669 SCV001134107 pathogenic not provided 2019-04-13 criteria provided, single submitter clinical testing The best available variant frequency is uninformative. Found in at least one symptomatic patient. Predicted to have a damaging effect on the protein. Occurs in multiple cases with a recessive pathogenic variant in the same gene. Assessment of experimental evidence suggests this variant results in abnormal protein function.

Sources cited for classification include the following: PMID 18456578 and 23974870. Classification of NM_000492.3(CFTR):c.1055G>A(R352Q) is based on the following criteria: This is a well-established pathogenic variant in the literature that has been observed more frequently in patients with clinical diagnoses than in healthy populations. Please note: this variant was assessed in the context of healthy population screening.‚Äã
Integrated Genetics/Laboratory Corporation of America RCV000007619 SCV001360485 pathogenic Cystic fibrosis 2019-10-07 criteria provided, single submitter clinical testing Variant summary: CFTR c.1055G>A (p.Arg352Gln) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.4e-05 in 251124 control chromosomes (gnomAD). c.1055G>A has been reported in the literature in multiple individuals affected with Cystic Fibrosis (e.g. Dupuis_2015, Shackelton_1994, Sosnay_2013). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function, and demonstrated that the variant leads to defective chloride channel function (Sosnay 2013). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and all of them classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
