HLA 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...
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 کاملLinkage 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 کاملExtensive clinical experience: nonclassical 21-hydroxylase deficiency.
CONTEXT Nonclassical congenital adrenal hyperplasia (CAH) owing to steroid 21-hydroxylase deficiency (NC21OHD) is the most frequent of all autosomal recessive genetic diseases, occurring in one in 100 persons in the heterogeneous New York City population. NC21OHD occurs with increased frequency in certain ethnic groups, such as Ashkenazi Jews, in whom one in 27 express the disease. NC21OHD is u...
