The FMR1 gene provides instructions for making a protein called fragile X mental retardation 1 protein, or FMRP. This protein is present in many tissues, including the brain, testes, and ovaries.ragile X syndrome-caused by mutations in the FMR1 gene. Almost all cases of fragile X syndrome are caused by an expansion of the CGG trinucleotide repeat in the FMR1 gene. In these cases, CGG is abnormally repeated from 200 to more than 1,000 times, which makes this region of the gene unstable.
