New compound heterozygous mutations of p. Thr101Ilefs 2 and p. Thr306Ale in a child from a Chinese family with 17α-hydroxylase/17, 20-lyase deficiency.

Abstract excerpt

We determined whether a child with 17α-hydroxylase/17, 20-lyase deficiency possessed the sex-determining region (SRY) gene, and examined the mutations present in the CYP17A1 gene that led to 17α-hydroxylase/17, 20-lyase deficiency. In the child, karyotype analysis was performed and polymerase chain reaction analysis and electrophoretic techniques were used to identify the SRY gene. A total of 50 normal...
