Ellen McDonagh (Genomics England Curator)

Comment on list classification: This gene has been promoted from Amber to Green, for the biallelic mode of inheritance, due to comments from Dr Ellen Thomas that exocrine pancreas dysfunction is an indication for diagnostic Cystic Fibrosis testing, and therefore this panel should cover the CFTR gene.
Created: 7 Dec 2018, 9:23 a.m.
Comment on mode of inheritance: Changed to the biallelic form.

In OMIM CFTR is associated with a susceptibility to {Pancreatitis, hereditary}.

Numerous candidate gene association studies have shown that CFTR variants are overrepresented in chronic pancreatitis (PMID: 9725921;15987793;16134171;16193325;11729110;23951356;22427236;25033378). These are reviewed by Ooi and Durie (2012) (PMID: 22658665) and Hegyi et al (2016)(PMID: 26856995).

In a review of hereditary pancreatitis Raphael and Willingham (2016) (PMID: 27555793) state that autosomal recessive inheritance of severe homozygous mutations, such as F508-delta/F508-delta, results in the typical multisystem cystic fibrosis phenotype that most often includes early-onset pancreatic insufficiency. Patients with this type of inheritance rarely develop recurrent acute pancreatitis in the form of HP (PMID: 1345141). Conversely, inheritance of one of the mild variants of CFTR, such as the R75Q mutation, is associated with a more limited cystic fibrosis syndrome and a greater incidence of pancreatitis (PMID: 15749233). Additionally, nine CFTR mutations associated with a deficiency in bicarbonate conductance (known as CFTR–BD mutations) were identified carrying a risk of acute and chronic pancreatitis in the setting of an otherwise mild cystic fibrosis syndrome (PMID: 25033378 ). Some CFTR mutations can be inherited in a complex-type pattern. When a patient is heterozygous with, for example, one CFTR mutation and an additional genetic mutation, such as SPINK1 or CTRC, the risk of pancreatitis is increased (PMID: 20977904;22427236).
