The Becker's Muscular Dystrophy (BMD) is a disease with similar aspect and distribution to the Duchenne Muscular Dystrophy (DMD), although it is usually less severe. The main purpose of this investigation was to outline the most important clinical characteristics that can help in the differential diagnosis between these two diseases. Thirty eight patients were studied; 16 with BMD and 22 with DMD. Clinically both are very similar, and the best criteria for the differentiation of this two diseases is the inability to walk. The age of symptomatology onset was 10.5 +/- 7.2 years in BMD and 2.3 +/- 13 years in DMD showing an overlapping of 18.42% of DMD and DMB at the age of 4, this overlapping difficult the precise diagnosis between both diseases. The creatine kinase (CK) study was not relevant.

The main goal of this study was to determine and characterise the types of mutations in two monogenic human disorders: cystic fibrosis (CF) and Duchenne/Becker muscular dystrophy (DMD, BMD) and the susceptibility allele frequency in a polygenic disease: type I insulin-dependent diabetes mellitus (IDDM). After analysing 220 chromosomes for mutations in the CF (Cystic Fibrosis Transmembrane Conductance Regulator = CFTR) gene, delta F508 mutation was most abundant (41%) and out of the non-delta F508 CF mutations 5% was identified as G542X, G551D, R553X, N1303K and W1282X. The CF haplotype analysis by using linked markers to the CFTR gene revealed that the CF "B" haplotype occurred in 66.7% of patients, and this haplotype was 57.2% in patients carrying the delta F508 mutation. Prenatal genetic diagnosis for CF was performed in 10 fetuses: 3 were affected, 6 were carriers, and 1 without any CF mutation. Fifty % of 66 patients with DMB/BMD muscular dystrophy had one or more exon deletions in the dystrophin gene. Eighty-five % of the deletions occurred at the 3' and 15% at the 5' end of the gene. Out of the three prenatal diagnosis in one case DMD was substantiated. Thirty-six % of 50 patients with IDDM possessed four, 44% three and 20% two susceptibility markers in the HLA-DQA1, -DQB1 region. The onset of the disease correlated with the number of susceptibility alleles.
