The frequencies of haplotypes in block 1 and their association with HD.

aGenotyping of several loci in several people failed, and their haplotypes were not determined.
bSNPs 1–6 that comprise a haplotype are: in order, rs274618, rs274622, rs1990040, rs13242038, rs724226, rs2189814. Haplotypes with a frequency <0.01 were excluded.
cP-value was calculated by 2×2 chi-squared tests (carrier with a given haplotype vs. non-carrier ).
dOR and 95% CI were calculated by logistic regression analysis with adjustment for demographic factors, including age, gender, education level, unemployment, and life history with family. Statistically significant results with an FPRP value <0.2 are marked in bold.
