Abstract
Severe clinical signs of Fabry''s disease were observed in 4 of 8 heterozygous daughters of a male patient. Activities of .alpha.-galactosidase A in serum, white blood cells, and hair roots of the manifesting carriers were markedly lower than 50% of normal. These findings are not easy to interpret in terms of random X inactivation alone; several alternative models including nonrandom (preferential) X inactivation are discussed.
