Description

In an 8-year-old boy of Turkish origin, born of consanguineous parents, with congenital adrenal hyperplasia due to steroid 11-beta-hydroxylase deficiency (202010), Helmberg et al. (1992) identified a homozygous 2-bp insertion in codon 394 in exon 7 of the CYP11B1 gene, resulting in a frameshift and a premature stop in codon 469, resulting in complete destruction of the enzyme's heme-binding domain. The patient had marked hypertension, precocious pseudopuberty, and completely virilized intersexual genitalia with a 46,XX karyotype. Ultrasound examination disclosed adrenal hyperplasia and the existence of a uterus and vagina ending in the proximal urethra. Four sibs of the patient died shortly after birth or in early childhood.
