Integrated Genetics/Laboratory Corporation of America RCV000007614 SCV000696815 pathogenic Cystic fibrosis 2017-02-23 criteria provided, single submitter clinical testing Variant summary: The CFTR c.1013C>T (p.Thr338Ile) variant involves the alteration of a conserved nucleotide. 5/5 in silico tools predict a damaging outcome for this variant. This variant was found in 5/121336 control chromosomes at a frequency of 0.0000412, which does not exceed the estimated maximal expected allele frequency of a pathogenic CFTR variant (0.0129603). The variant has been reported in numerous affected individuals in the literature, and has been shown to result in <10% chloride conductance compared to WT. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.

Sources cited for classification include the following: PMID 18456578 and 23974870. Classification of NM_000492.3(CFTR):c.1013C>T(T338I) 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.
