Linkage and association between HLA and 21-hydroxylase deficiency.
Congenital adrenal hyperplasia because of 21-hydroxylase deficiency is closely linked to the HLA system. The lod scores in 14 informative families are presented. Apart from linkage, the 21-hydroxylase deficiency is associated with an increase of BW47 antigen and lack of B8 antigen in patients. A family with a possible recombination between the 21-hydroxylase deficiency and the HLA complex was f...
متن کاملHLA Haplotype Associated with 21-Hydroxylase Deficiency
We have segregated DRI+ individuals into two categories according to whether or not their class II+ cells stimulated T lymphocyte clones specific for or restricted to DR1. In a majority of cases (87%), failure to stimulate was a property of cells having the B14;DR1 haplotype and/or nonclassical 21-hydroxylase deficiency. Absence of clonal proliferation could not be explained by release of an in...
متن کاملHeterogeneity in the gene locus for steroid 21-hydroxylase deficiency.
DNA was analysed from 33 patients with congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency. In each case Southern blots were prepared from a number of restriction enzyme digests and hybridised with probes for both the 21-hydroxylase and the adjacent fourth component of complement (C4). Evidence for deletion of the active 21-hydroxylase gene (CYP21B) was found in 13 cases and...
متن کاملTreatment and Outcome of Congenital Adrenal Hyperplasia: 21-Hydroxylase Deficiency
The use of glucocorticoids to treat individuals with congenital adrenal hyperplasia (CAH) was first reported by both Wilkins and Bartter in 1950. Since that time, the care of these patients has improved dramatically, and through the efforts of dedicated medical researchers, it continues to improve today. With early detection by newborn screening, initiation of treatment in infants with salt-was...
متن کاملHLA class I-, complement C4- and 21-hydroxylase probes in the genetic analysis of 21-hydroxylase deficiency.
In order to develop an optimal strategy for the prenatal diagnosis of steroid 21-hydroxylase (EC 1.14.99.10) deficiency, we investigated 16 affected families with salt wasting syndrome. Genomic DNA derived from peripheral white blood cells was digested with 6 different restriction enzymes. Hybridisation was carried out with DNA-probes of the HLA class I region, the 21-hydroxylase- and the compl...
