WebSep 1, 2008 · The inbreeding coefficient (F(is)) is a measure of the degree and direction of deviation from HWE. Among studies investigating SNPs, there was a significant correlation between F(is) and HWD (R = 0.191; p = 0.002), indicating that the greater the deviation from HWE, the greater the deficit of heterozygotes. WebJun 12, 2024 · The deviations from the HWE for the PCSK9 rs505151 and rs11591147 genotype distributions were assessed by Fisher’s exact test. A p < 0.05 for the test was considered deviated from the HWE. The pooled SMD with 95% confidence interval (CI) was applied to calculate the differences of plasma lipid levels between different genotypes.
