Frequencies for the pathogenic mutations

Mutation	Absolute allele frequency	Relative allele frequency (%) prevalence
p.F508del	15	20.27
p. H609R	14	18.92
p. G85E	6	8.11
p.G970S	3	4.05

There were patients with two of these mutations, so the absolute allele frequency is not the number of patients. The total allele frequency was calculated with 37 patients with two chromosomes each.
