2Pregnancy
If mothers with Rett syndrome are pregnant, they would pass the disorder to the babies, whether they are girls or boys. The condition would be inherited from normal moms with a germline mutation in a gene encoding MeCP2. The mutation is believed to trigger a protein deficiency, which prevents the body and brain cells from functioning normally. In many cases, it can be characterized by early epilepsy or infantile spasms. It is estimated that Rett syndrome occurs in 1 out of 12,500 females by the age of 12. [2]
