17alpha-Hydroxylase deficiency (17OHD) is an autosomal recessive disorder that produces an excess of mineralocorticoids and sexual differentiation abnormalities. Using DNA sequencing analysis of the 17alpha-hydroxylase (CYP17) gene from a Japanese patient with 17OHD, we identified a new type of genetic abnormality in this disease, a G to A transition at position +5 in the splice donor site of intron 7 of the CYP17 gene. In vitro expression analysis of an allelic minigene that consists of exons 6-8 of the patient's CYP17 gene showed that the transition causes the skipping of exon 7. This exon skipping alters the translational reading frame of exon 8 and introduces a premature stop codon (TAA) at amino acid position 410 proximal to the heme iron-binding site essential for the enzymatic activity of CYP17. Restriction enzyme analysis showed that the patient is homozygous for the mutated CYP17 gene, and the parents are heterozygotes. This is the first reported patient with 17OHD caused by the splice site mutation in the CYP17 gene.
