Myriad Women's Health, Inc. RCV000056394 SCV001194201 pathogenic Cystic fibrosis 2019-12-04 criteria provided, single submitter clinical testing NM_000492.3(CFTR):c.532G>A(G178R) is classified as pathogenic in the context of cystic fibrosis and is associated with classic disease. Sources cited for classification include the following: PMID 18456578, 9305991, 23381846 and 23974870. Classification of NM_000492.3(CFTR):c.532G>A(G178R) 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.
Integrated Genetics/Laboratory Corporation of America RCV000056394 SCV001363743 pathogenic Cystic fibrosis 2019-04-05 criteria provided, single submitter clinical testing Variant summary: CFTR c.532G>A (p.Gly178Arg) results in a non-conservative amino acid change located in the ABC transporter type 1, transmembrane domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. One computational tool predict the variant creates a 3' acceptor site. Consistent with this prediction, one functional study showed that this variant led to a significant skipping of exon 5 (Raynal_2013). The variant allele was found at a frequency of 1.2e-05 in 168188 control chromosomes. c.532G>A has been reported in the literature in multiple individuals affected with Cystic Fibrosis (Zielenski_1991, Cremonesi_1992, Heim_2001, Sugarman_2004, Ooi_2012, Sosnay_2013, DeBoeck_2014). These data indicate that the variant is very likely to be associated with disease. Multiple publications report experimental evidence evaluating an impact on protein function (Seibert_1997, Choi_2001, Yu_2012, Sosnay_2013). The most pronounced variant effect results in <10% of normal activity. 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. Based on the evidence outlined above, the variant was classified as pathogenic.
