ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000515132 SCV000608288 pathogenic Pancreatitis 2017-10-24 criteria provided, single submitter clinical testing The CFTR c.1523T>G; p.Phe508Cys variant has been published in the literature in individuals with monosymptomatic atypical cystic fibrosis (congenital bilateral absence of the vas deferens, pancreatitis) who also carried an additional pathogenic variant (Dork 1997, Havasi 2008, Ooi 2012). Additionally, our own internal data shows this variant is enriched in individuals with CFTR-related disease. However, this variant has also been published in asymptomatic individuals who also carried an additional pathogenic variant (Desgeorges 1994, Kobayashi 1990). The variant has been described in the dbSNP variant database (rs74571530) with an allele frequency of 0.1512 percent in European Americans in the Exome Variant Server and an allele frequency of 0.1609 in Europeans in the Exome Aggregation Consortium. The phenylalanine at codon 508 is well conserved across species and computational programs (PolyPhen2, SIFT) predict this variant is deleterious to protein function. Taken together, we predict this variant to be a very mild pathogenic variant that will not cause classic cystic fibrosis.

Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: Benign by Emory. Compund heterozygotes foe this variant and %508del variant were clinically normal, therefore this variant has been classified as benign by Kobayashi et al 1990. Frequency of the variant was higher in individuals with CBAVD (Havasi 2008). Phenotype does not meet reporting criteria.
