title: Association of the spectral features of heart period signal with SNP of NOS in the Chinese Han nationality population.
abstract: To explore association of the spectral features of heart period signal with SNPs at 5 sites of NOS gene in the subjects (male89, female77, aged 62.40+/-2.5 yrs) by allele specific primer PCR technique. It was found that the TT allelic genotype of NOS2 C-1173T associated with the highest RPH and TT allelic genotype of NOS3 G894T associated with the highest APH in HPS spectral parameters. This suggests the SNPs of NOS2 C-1173T and NOS3 G894T may be the deep layer factors to result in the variability of HPS spectral parameters.
