Tightly bound fatty acids in the erythrocyte membrane proteins in myotonic dystrophy.

The composition of "tightly bound fatty acids" and of loosely bound fatty acids in the erythrocyte membrane proteins from patients with myotonic dystrophy were compared with those of sex- and nearly age-matched normal controls. No significant differences could be detected in the composition of tightly bound fatty acids and there was no gross abnormality in the composition of loosely bound fatty acids between myotonic dystrophy patients and normal controls, although small differences were observed.
