Notes

Individuals homozygous or heterozygous for the rs11959298(A)-rs6596189(C) haplotype risk allele were 2.54 and 1.59 fold more likely to have autism, respectively, compared to rs11959298(G)-rs6596189(T) carriers. Note/caveat emptor: ~90% of the world's population carries what the authors from this for-profit genetic testing company call the "risk haplotype", yet the frequency of autism is less than 1% (perhaps 1 in 150).
