Several clinical and animal studies indicate that essential hypertension is
inherited as a multifactorial trait with a significant genetic and environ
mental component. In the stroke-prone spontaneously hypertensive rat model,
investigators have found evidence for linkage to blood pressure regulatory
genes (quantitative trait loci) on rat chromosomes 2, 10, and X. In 1 huma
n study of French and UK sib pairs, evidence for linkage has been reported
to human chromosome 17q, the syntenic region of the rat chromosome 10 quant
itative trait loci (QTL). Our study confirms this linkage (P=0.0005) and re
fines the location of the blood pressure QTL.
