Differences in allele frequencies
between Tamilian and other ethnic populations were assessed by Fisher's exact and chi-square tests.
As shown in Table 2, there was no significant difference between the major depressive disorder and control groups after the analysis of genotype and allele frequencies
of the Gly389Arg polymorphism in the ADRB I gene (p=0.
The other loci showed deviations at one or a maximum of two populations, and null allele frequencies
that ranged from 0.
The distribution of genotype and allele frequencies
in overall and sex-specific RA patients (RA positive and RA negative) and controls in cohort 1 and cohort 2 are represented in Table 2.
Genetic variation: We determined allele frequencies
1980) of each marker was estimated from observed allele frequencies
in each species.
Ball-park null allele frequencies
were estimated from the number of apparent null allele carrying 'parents' and the total number of (non-excluded) parents in the database after correcting for ascertainment bias.
The allele frequencies
of 2 additional SNPs [the intronic SNP rs1810020 (A to G) and the 3' untranslated region SNP rs2659122 (C to T)] were significantly different from frequencies reported by Parikh et al.
Minor allele frequencies
between groups were compared with a test of binomial proportions.
tried to determine allele frequencies
and genotype distributions for some autoimmune blood diseases.
The genotype distributions and allele frequencies
for the polymorphisms investigated in healthy volunteers, patients with normal coronary arteries and single vessel and multivessel disease groups were compared by Chi-square analyses.
The observed genotype and allele frequencies
were in agreement with the frequencies predicted by the Hardy-Weinberg equilibrium ([chi square] = 1.
