Reliability of the Booth-Nadler technique for the detection of Hunter heterozygotes

Skin fibroblasts from three obligated and one potential heterozygotes for the Hunter gene displayed abnormal metabolism of glycosaminoglycans four to six weeks after rapid freezing in liquid nitrogen. The technique seems to be useful for the identification of Hunter carriers, especially when the degradation of 35SO4-labeled, intracellular glycosaminoglycans, rather than the uptake of 35SO4, is measured.
