Early diagnosis and intensive intervention offer the best prognosis for individuals with fragile X syndrome. Adults with fragile X syndrome may benefit from vocational training and may need to live in a supervised setting. Life span is typically normal
No, fragile x syndrome is not progressive
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.
affects males and females of all ethnic groups. It is estimated that there are about one in 4,000 to one in 6,250 males affected with fragile X syndrome. There are approximately one-half as many females with fragile X syndrome as there are males
No. Fragile X Syndrome is not deadly. People with FXS live a normal life span. For more information on FXS go to the website for the M.I.N.D. Institute at UC-Davis.
Fragile X syndrome is caused by a mutation that prevents the Fragile X mental retardation (Fmr-1) gene from being transcribed. This gene is located on the X chromosome (the sex chromosome). Since males only carry one of these chromosomes, they are twice as likely to be affected by the mutation than females.
Martin Bell Syndrome.
also known as Martin-Bell syndrome, Marker X syndrome, and FRAXA syndrome

A non-repeat mother without fragile X syndrome cannot pass the condition to her male offspring. Fragile X syndrome is caused by mutations in the FMR1 gene, specifically the expansion of CGG repeats, which typically occurs in carriers with a certain number of repeats. Since the mother does not have the syndrome or carry the premutation, her male offspring would not inherit the genetic mutation associated with fragile X syndrome.
