Rett Sydrome and Vitamin D

Rett Syndrome is a very rare developmental disorder. It is caused by a mutation of the X chromosome on a gene called MECP2. This disorder leads to a loss of hand functionality, slow brain growth, problems with walking, and seizures. It is often misdiagnosed as cerebral palsy, non-specific developmental delay or autism.

Researchers in Serbia have found that people with Rett syndrome have very low vitamin D levels, which is likely due to the amount of anti-seizure medication they take. Patients that were taking multiple anti-seizure medication were 3.3 times likely to have a greater chance of having severe vitamin D deficiency.
