Fragile X Sydrome is a genetic disorder affecting the X chromosome in males and females. This disorder makes the CGG codon repeat many times in the FMR1 gene on the X chromosome.
Fragile X can cause a variety of symptoms. If cases worsen, mental disabilities like autism can happen.
Fragile X is more prominent in men, however it is still possible in women. This is because women need about 200 repeats of the CGG gene, while men only need 50-100.
A DNA test is usually done at birth, and some physical changes may be present.
There is a treatment with therapy but no cure available. It is a recessive trait, so it's ranked uncommon with 200,000 cases worldwide.
