One of the best-known genetic mutations, rs113993960 is also called delta508 or delta F508. It results in the loss of a phenylalanine (F) residue at amino acid position 508 of the cystic fibrosis CFTR gene. As first reported in 1989, about 70% of all cystic fibrosis patients carry this mutation. [PMID 2567116OA-icon.png]


Cystic fibrosis is inherited in a recessive manner, so homozygotes for rs113993960(-;-), and less commonly, compound heterozygotes carrying one rs113993960(-) allele in addition to one other nonfunctional CFTR variant, are prone to developing cystic fibrosis.
