This condition causes a range of developmental problems including learning disabilities and cognitive impairment. It is the most common form of inherited intellectual disability in males and a significant cause of intellectual disability in females.
Fragile X syndrome is caused by a change (mutation) in a gene on the X chromosome’s long arm (Xq27.3). The gene is called fragile X mental retardation 1 (FMR-1). The syndrome is the most common hereditary cause of mental retardation and is passed on through X-linked recessive inheritance. Diagnosis is made through DNA-analysis of blood samples.

Gruvgång mina
Fragile X syndrome is a genetic disorder which occurs as a result of a mutation of the fragile X mental retardation 1 (FMR1) gene on the X chromosome, most commonly an increase in the number of CGG trinucleotide repeats in the 5' untranslated region of FMR1. Fragile X syndrome is inherited in an X-linked dominant pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes.
Genetic tests
Fragile X syndrome is a genetic disorder caused by a change to one of the genes on the X chromosome. It is the most common inherited cause of intellectual disability. Fragile X syndrome is also linked to features of autism spectrum disorder. Fragile X syndrome affects around 1 in 3,600 boys and between 1 in 4,000 – 6,000 girls.

This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should. FXS can affect both sexes.
