Fragile X syndrome is defined as a genetic disease, results in cognitive impairment and mental problems.
It is caused by a mutation in FMR1 gene that causes an increase in the CGG trinucleotide units in the gene. This is an example of insertion mutation as it involves addition of nucleotide sequences to the gene.
