Description

The CFTR c.3718-2477C>T variant is predicted to interfere with splicing. This variant is also referred to as 3849+10kbC>T or c.3717+12191C>T. This variant has previously been reported to be causative in multiple cystic fibrosis patients with a mild phenotype (Highsmith et al. 1994. PubMed ID: 7521937; McKone et al. 2003. PubMed ID: 12767731; Duguépéroux et al. 2005. PubMed ID: 15738290; Sosnay et al. 2013. PubMed ID: 23974870; cftr2.org) and is included in the American College Medical Genetics (ACMG) panel of CF variants (Watson et al. 2004. PubMed ID: 15371902; Deignan JL et al. 2023. PubMed ID: 37310422). We classify this variant as pathogenic.
