Association studies for NPY gene exon 2 (+1128 T/C), promoter (−399 T/C) and IL1B gene promoter (−511 C/T) polymorphisms in active and stable vitiligo patients from Gujarat.

‘n’ represents number of Patients/ Controls, HWE refers to Hardy-Weinberg Equilibrium, (AV) refers to Active Vitiligo, (SV) refers to Stable Vitiligo, (C) refers to Controls and CI refers to Confidence Interval.aActive Vitiligo vs. Controls using the chi-squared test with 3×2 contingency table,bStable Vitiligo vs. Controls using the chi-squared test with 3×2 contingency table,cActive Vitiligo vs. Controls using the chi-squared test with 2×2 contingency table,dStable Vitiligo vs. Controls using the chi-squared test with 2×2 contingency table.Odds ratio is based on allele frequency distribution. Statistical significance was considered at p value ≤0.017 due to Bonferroni's correction for multiple testing.Association studies for NPY gene exon 2 (+1128 T/C), promoter (−399 T/C) and IL1B gene promoter (−511 C/T) polymorphisms in active and stable vitiligo patients from Gujarat.
