H. Grasemann et al., Simple tandem repeat polymorphisms in the neuronal nitric oxide synthase gene in different ethnic populations, HUMAN HERED, 49(3), 1999, pp. 139-141
Allelic frequencies of a CA dinucleotide repeat in exon 29 and an intronic
AAT trinucleotide repeat in the neuronal nitric oxide synthase (NOS1) gene
were determined by simple sequence length polymorphism (SSLP) in 305 Americ
an-Caucasian and 105 African-American healthy subjects, There were highly s
ignificant differences in allele frequencies between the two ethnically div
erse study populations.
