nearly all instances of Rett syndrome are due to a mutation (a change in the DNA) in the MECP2 gene, that is found at the X chromosome (one of the intercourse chromosomes).

The MECP2 gene carries commands for producing a particular protein (MeCP2), which is wanted for mind development. The gene abnormality prevents nerve cells within the mind from running properly.

there may be commonly no own family history of Rett syndrome, which means that it is not surpassed on from one era to the following. almost all cases (over 99%) are spontaneous, with the mutation going on randomly. that is referred to as a 'de novo' mutation.
