title: Carrier detection in Sanfilippo A syndrome.
abstract: Leucocytes or fibroblasts from 10 obligate heterozygotes for Sanfilippo A syndrome gave decreased heparan N-sulphatase levels, using a modification of the method of Hall et al. (1978), which did not overlap normal control values. Five family members gave decreased values and are presumed heterozygotes.
