Results of association between 5 SNPs in ATP2B2 and autism and haplotype analyses in 427 trios of Han Chinese descent.

Afreq, allele frequency; Families, number of informative families; S, test statistics for the observed number of transmitted alleles; E(S), expected value of S under the null hypothesis (i.e., no linkage and no association).aThe number of permutationS is 10,000;bwhole marker permutation test using minimal p (when only one haplotype was significant).
