Abstract excerpt
To investigate whether unusual allele segregation might explain the dominant negative effect of the expanded allele for myotonic dystrophy on myotonin protein kinase mRNA metabolism, which is suggested to cause the disease, we determined the number of CTG repeats at the DM locus in the nonaffected alleles of 64 DM (dystrophia myotonia) patients. The relative distribution was then compared with the distributions...
