Abstract:
Objective:To improve the understanding of 17α-hydroxylase/17, 20-lyase deficiency(17OHD)disease.
Methods:The clinical data of six patients suffering from 17OHD were analyzed retrospectively.
Results:Two patients with complete combined defect had typical clinical presentations, including absence of secondary sexual characteristics, primary amenorrhea, hypertension, hypokalamia, lower gonadal hormone levels, as well as elevated corticotropin and progesterone levels. TAC329AA homozygous mutation, IVS1+ 2T>C, and c. 775_776delAT complex heterozygous mutation were found in 2 cases. Four cases of partial combined defect showed high progesterone, lower gonadal hormones and dehydroepiandrosterone-sulfate levels. Three females(46, XX)showed spontaneous menstrual and primary infertility, and two of them got successful pregnancy with assisted reproductive technology. TAC329AA heterozygous mutation was found in those 4 cases.
Conclusions:TAC329AA mutation is common in 17OHD, and heterozygous or homozygous mutation of TAC329AA may be the genetic and molecular basis for determining whether these patients present as partial or complete defect. The elevated plasma progesterone in non-pregnancy combined with lower gonadal hormones and dehydroepiandrosterone-sulfate is the main character of patients with partial 17OHD. Less severe patients may be able to get successful pregnancy with assisted reproductive technology.
