Carriership of a defective tenascin-X gene in steroid 21-hydroxylase deficiency patients: TNXB -TNXA hybrids in apparent large-scale gene conversions [PDF]

open access: yes, 2002
Steroid 21-hydroxylase deficiency is caused by a defect in the CYP21A2 gene. CYP21A2, the adjacent complement C4 gene and parts of the flanking genes RP1 and TNXB constitute a tandemly duplicated arrangement in the central (class III ...

A missense mutation at Ile172----Asn or Arg356----Trp causes steroid 21-hydroxylase deficiency.

open access: yesJournal of Biological Chemistry, 1990
Congenital adrenal hyperplasia (CAH) is a common recessive genetic disease caused mainly by steroid 21-hydroxylase (P450c21) deficiency. Many forms of CAH exist resulting from various mutations of the CYP21B gene.

Perturbations in Lineage Specification of Granulosa and Theca Cells May Alter Corpus Luteum Formation and Function [PDF]

open access: yes, 2019
Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to be fertilized and a corpus luteum is not formed.
