}}[[rs199826652]] represents the same 3 basepair deletion of the amino acid Phe at position 508 of the [[CFTR]] protein, which is commonly known as delta508, as [[rs113993960]]. This SNP therefore also represents the [[CFTR]] mutation representing ~70% of all [[cystic fibrosis]] cases.

Both SNPs exist in dbSNP. In SNPedia, the main annotation is at [[rs113993960]], since it is the name more commonly reported in results from microarray platforms.

[[rs199826652]] is more likely to be reported in sequencing data, though, due to the left justification of indels as specified in the VCF 4.1 (sequence) file format specification released in 2011.
