Genotype of Yupik Eskimos with congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Abstract

An A-to-G transition in the second intron was the sole mutation detected in four Yupik Eskimo patients with salt-wasting congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency. Allele-specific hybridization should be an efficient means of performing prenatal diagnosis of the disease in this highly inbred population.
