what does fragile x syndrome do to the body
âFragile X syndromeâ is also known as Fragile X. It is the most common genetic form of mental retardation. It occurs due to changes in a gene which is passed on from one generation to the other. It can affect people belonging to all income levels and ethnic groups.
Fragile X syndrome is associated with the expansion of the CGG trinucleotide repeat affecting the Fragile X mental retardation 1 (FMR1) gene on the X chromosome, resulting in a failure to express the fragile X mental retardation protein (FMRP), which is required for normal neural development.
