Table 1. Haplotype characteristics.

Haplotype	CGT	GAC	CGC	p value
N	34	25	2	–
Age range (yr)	15–58	18–53	38–39	–
Age (yr)	35±12	36±10	39±1	0.83
Post-mortem interval	27±12	24±5.8	28±3.2	0.45
RNA integrity number	6.4±0.87	6.2±0.80	5.2±1.13	0.44
Brain tissue pH	6.5±0.3	6.5±0.3	6.7±0.2	0.52
Frequency	0.664	0.27	0.06	–

The haplotype frequencies were comparable to those specified in the CEU HapMap dataset. Subjects did not differ in terms of age, post-mortem interval, RNA integrity number, or brain tissue pH. Values represent mean ± standard deviation. Haplotypes reconstructed based on rs174548, rs174549, and rs174555. As only 2 subjects had the CGC haplotype, they were excluded from the subsequent analyses.
