[Erythrocyte membrane in Duchenne muscular dystrophy. I. Sensitivity to lysolecithin in dystrophic patients and their families].

The percentage of echinocytes in the blood from patients affected by Duchenne muscular Distrophy was studied after red cells treatment with L-alpha-lysophosphatidylcholine. The echinocyte content was significantly higher in Duchenne patients and in the components of their families, as previously demonstrated is lower in Stainert patients. The sensitivity to lysophosphatidylcholine in Duchenne muscular Distrophy is a diagnostic test for carrier condition
