1 doctor agrees

In brief: Triplet repeats....

All three are caused by a form of genetic instability involving dna triplet repeats, however they affect three different genes and cause three different diseases: freidrich's = degenerative neuro-muscular disorder; fragilex = mental retardation and behavioral disorder; and myotonic = progressive muscle wasting and weakness.
