*

r is excess of fathers carriers compared to mother carriers.

P-values test the hypothesis that the excess paternal prevalence is positive, and are based on an exact permutation test.

ǂ

The 95% CI does not completely match with the p-value, because it is a two-sided approximate interval, while the test is one-sided and exact.

§

p is carrier prevalence of each SNP per 1000 people.
