What is X-Linked Alpha Thalassemia Mental Retardation Syndrome (ATR-X)?

ATR-X is an X linked condition, which means the gene involved lies on the X chromosome. Only males are affected by this disorder (they only have one X chromosome which is always inherited from their mothers), females can be carriers but are not affected themselves (they have two X chromosomes and the normal chromosome fully compensates).

If a woman is a carrier there is a 50:50 chance of her passing on the affected X chromosome, if she passes it onto a boy he will be affected, if she passes it on to a girl she will be a carrier.
