This disease was shown to have increased correlation with celiac disease by studies following Dorothy Hansine Andersen’s (-5[1])research on how it affects the pancreas. This disease is treated by modulators like ivacaftor (15[1])and lumacaftor. (15[2])The A·B·C·C·7 (-5[1])gene codes for an ABC-class (-5[1])transporter for ions (15[1])like thiocyanate whose malfunction is a hallmark (15[1])of this disease. (15[1])This disease is caused by a mutation in the first (15[1])nucleotide-binding domain of a (*) transmembrane (10[1])conductance (10[3])regulator, (10[2])in which (10[4])phenyl·alanine (10[2])508 (10[2])is (10[1])deleted. (10[7]-5[1])It’s not (10[1])sickle cell (10[1])anemia, (10[1]-5[1])but heterozygous (10[1])advantage (10[1])from the mutation that causes this disease confers resistance against cholera. (10[3])Abnormal (10[2]-5[1])salt levels (10[1])in a sweat test (10[1])are used to diagnose (10[1]-5[1])this autosomal (10[2]-5[1])recessive (10[1])disease.
