Molecular diagnosis of 21-hydroxylase deficiency: detection of four mutations on a single gel.

Abstract excerpt

Previous studies of the molecular basis of 21-hydroxylase deficiency have shown four common gene conversion mutations in exons 7 and 8. Current molecular diagnostic protocols use allele-specific oligonucleotide hybridization (ASOH) to individually detect each of these mutations and the corresponding normal alleles. This method is costly, labor intensive, and may not provide quantitative results. To expedite...
