For example, fragile X syndrome is due to the replication of the sequence CGG 55 230 times in the 5′ untranslated region of the FMR 1 gene. If this trinucleotide is found in this frequency, the individual will suffer the symptoms of the disease, which include mental retardation. Myotonic dystrophy is also another example of a trinucleotide repeat disease the affected MDPK gene will have multiple copies of the sequence CTG in part of its gene that encodes for the…
