Evaluation of carrier detection of Duchenne muscular dystrophy using carbonic anhydrase III and creatine kinase.
Carbonic anhydrase III (CAIII) and creatine kinase (CK) were measured in plasma samples from a series of females at-risk as carriers of Duchenne muscular dystrophy and compared with control groups. Both plasma CAIII and CK levels were raised in a proportion of carriers. Although measurement of CAIII and CK was no more successful in identifying carriers than CK alone, CAIII could fulfill a useful confirmatory role, particularly for cases with a marginally elevated CK or where the sample is poorly preserved. The difference between the CK and CAIII results could indicate biochemical heterogeneity in the expression of Duchenne muscular dystrophy.
