Abstract
17α-hydroxylase deficiency is a type of congenital adrenocortical hyperplasia that is typically diagnosed in childhood or adolescence. It manifests as hypertension with gonadal dysfunction as the primary symptom. We herein report 17α-hydroxylase/17,20-lyase deficiency (17OHD) diagnosed at the age of 45 years. The patient presented with hypertension, irregular menstruation, and hyperaldosteronism. The clinical manifestations of 17OHD vary based on the specific variant pattern of CYP17A1. In this case, the variant was c.157_159 TCC del p. Phe53del, which has been frequently reported in Japan. The enzymatic deficiency due to this variant is partial, leading to a delay in making a correct diagnosis.
