Skin biopsies from the mother of a classical case of the Lesch-Nyhan syndrome grew only wild type fibroblasts. This suggested that she is not a heterozygous carrier of the mutant X-linked structural gene which causes the syndrome, and that a fresh mutation caused the disorder in her son. Evidence of mosaicism was sought in skin fibroblasts, hair follicles,(More)
A case of type 1 (adult) Gaucher's disease with a late onset tapeto-retinal degeneration and an initially dopamine responsive extrapyramidal syndrome is described.

Ten patients with varying degrees of hypothroid myopathy were studied clinically and by serial percutaneous needle muscle biopsies before and during treatment with L-thyroxine. The biochemical evidence of hypothyroidism was related to the severity of the myopathic and signs before treatment. The severity of myopathic symptoms before and during treatment(More)
