Deletion analysis of Duchenne muscular dystrophy using cDNA probes and multiplex PCR.

The authors studied Duchenne muscular dystrophy (DMD) in 14 Yugoslav families with 16 diseased men. All the sixteen patients showed typical phenotypic features of DMD. The linkage analysis was done with five probes 754, C7, PERT87.15, pERT87.30, and pERTBir. A deletion with pERT87.15 (DX 164) in one family was found. Deletion analysis was mainly performed using cDNA probes and multiplex PCR analysis. Preferential deletions were in the hot spot deletion region covered by cDNA probe 8. Among 14 examined patients with cDNA hybridization deletions were found in 5 cases (5/14). For quick and prenatal analysis the authors used multiplex PCR. With this methods deletions were found in 4 cases (4/15). The percentage of the observed deletions cases was 50% (8/16) in Yugoslav population, which shows good correlation with other European and American populations studied. Prenatal diagnosis was done for two consultants with highly ambiguous carrier risk, and no deletions were found.
