Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the CFTR gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis (PubMed:26823428). Mediates the transport of chloride ions across the cell membrane (PubMed:10792060, PubMed:11524016, PubMed:11707463, PubMed:12519745, PubMed:15010471, PubMed:12588899, PubMed:17036051, PubMed:19398555, PubMed:19621064, PubMed:22178883, PubMed:25330774, PubMed:1712898, PubMed:8910473, PubMed:9804160, PubMed:12529365, PubMed:17182731, PubMed:26846474, PubMed:28087700). Channel activity is coupled to ATP hydrolysis (PubMed:8910473). The ion channel is also permeable to HCO(3-); selectivity depends on the extracellular chloride concentration (PubMed:15010471, PubMed:19019741). Exerts its function also by modulating the activity of other ion channels and transporters (PubMed:12403779, PubMed:22178883, PubMed:22121115, PubMed:27941075). Plays an important role in airway fluid homeostasis (PubMed:16645176, PubMed:19621064, PubMed:26823428). Contributes to the regulation of the pH and the ion content of the airway surface fluid layer and thereby plays an important role in defense against pathogens (PubMed:14668433, PubMed:16645176, PubMed:26823428). Modulates the activity of the epithelial sodium channel (ENaC) complex, in part by regulating the cell surface expression of the ENaC complex (PubMed:17434346, PubMed:27941075, PubMed:17182731). Inhibits the activity of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G (PubMed:17182731). Inhibits the activity of the ENaC channel containing subunits SCNN1D, SCNN1B and SCNN1G, but not of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G (PubMed:27941075). May regulate bicarbonate secretion and salvage in epithelial cells by regulating the transporter SLC4A7 (PubMed:12403779). Can inhibit the chloride channel activity of ANO1 (PubMed:22178883). Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation (PubMed:19923167, PubMed:27714810). {ECO:0000269|PubMed:10792060, ECO:0000269|PubMed:11524016, ECO:0000269|PubMed:11707463, ECO:0000269|PubMed:12403779, ECO:0000269|PubMed:12519745, ECO:0000269|PubMed:12529365, ECO:0000269|PubMed:12588899, ECO:0000269|PubMed:14668433, ECO:0000269|PubMed:15010471, ECO:0000269|PubMed:16645176, ECO:0000269|PubMed:17036051, ECO:0000269|PubMed:1712898, ECO:0000269|PubMed:17182731, ECO:0000269|PubMed:19019741, ECO:0000269|PubMed:19398555, ECO:0000269|PubMed:19621064, ECO:0000269|PubMed:22178883, ECO:0000269|PubMed:25330774, ECO:0000269|PubMed:26627831, ECO:0000269|PubMed:26823428, ECO:0000269|PubMed:26846474, ECO:0000269|PubMed:27714810, ECO:0000269|PubMed:27941075, ECO:0000269|PubMed:28087700, ECO:0000269|PubMed:8910473, ECO:0000269|PubMed:9804160, ECO:0000305|PubMed:19923167}.;
Disease
DISEASE: Cystic fibrosis (CF) [MIM:219700]: A common generalized disorder of the exocrine glands which impairs clearance of secretions in a variety of organs. It is characterized by the triad of chronic bronchopulmonary disease (with recurrent respiratory infections), pancreatic insufficiency (which leads to malabsorption and growth retardation) and elevated sweat electrolytes. It is the most common genetic disease in Caucasians, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive. {ECO:0000269|PubMed:10094564, ECO:0000269|PubMed:11242048, ECO:0000269|PubMed:12167682, ECO:0000269|PubMed:12394343, ECO:0000269|PubMed:12529365, ECO:0000269|PubMed:1284466, ECO:0000269|PubMed:1284468, ECO:0000269|PubMed:1284529, ECO:0000269|PubMed:1284530, ECO:0000269|PubMed:1284548, ECO:0000269|PubMed:1379210, ECO:0000269|PubMed:15528182, ECO:0000269|PubMed:15716351, ECO:0000269|PubMed:16822950, ECO:0000269|PubMed:1695717, ECO:0000269|PubMed:1699669, ECO:0000269|PubMed:17098864, ECO:0000269|PubMed:1710600, ECO:0000269|PubMed:1712898, ECO:0000269|PubMed:17182731, ECO:0000269|PubMed:20008117, ECO:0000269|PubMed:20150177, ECO:0000269|PubMed:20691141, ECO:0000269|PubMed:2236053, ECO:0000269|PubMed:25330774, ECO:0000269|PubMed:26846474, ECO:0000269|PubMed:28001373, ECO:0000269|PubMed:28087700, ECO:0000269|PubMed:7504969, ECO:0000269|PubMed:7505694, ECO:0000269|PubMed:7513296, ECO:0000269|PubMed:7517264, ECO:0000269|PubMed:7520022, ECO:0000269|PubMed:7522211, ECO:0000269|PubMed:7524909, ECO:0000269|PubMed:7524913, ECO:0000269|PubMed:7525450, ECO:0000269|PubMed:7537150, ECO:0000269|PubMed:7541273, ECO:0000269|PubMed:7541510, ECO:0000269|PubMed:7543567, ECO:0000269|PubMed:7544319, ECO:0000269|PubMed:7581407, ECO:0000269|PubMed:7606851, ECO:0000269|PubMed:7680525, ECO:0000269|PubMed:7683628, ECO:0000269|PubMed:7683954, ECO:0000269|PubMed:8081395, ECO:0000269|PubMed:8406518, ECO:0000269|PubMed:8522333, ECO:0000269|PubMed:8723693, ECO:0000269|PubMed:8723695, ECO:0000269|PubMed:8800923, ECO:0000269|PubMed:8829633, ECO:0000269|PubMed:8910473, ECO:0000269|PubMed:8956039, ECO:0000269|PubMed:9101301, ECO:0000269|PubMed:9222768, ECO:0000269|PubMed:9375855, ECO:0000269|PubMed:9401006, ECO:0000269|PubMed:9443874, ECO:0000269|PubMed:9452048, ECO:0000269|PubMed:9452054, ECO:0000269|PubMed:9452073, ECO:0000269|PubMed:9482579, ECO:0000269|PubMed:9521595, ECO:0000269|PubMed:9554753, ECO:0000269|PubMed:9736778, ECO:0000269|PubMed:9804160, ECO:0000269|PubMed:9921909}.
