Malan syndrome is a multiple congenital anomalies syndrome. It is a rare genetic disorder that occurs because of change in the NFIX gene (nuclear factor I/X (CCAAT-binding transcription factor)) located on the short arm (“p” arm) of chromosome 19 at position 13.2. Its prevalence is less than 1 per million.

As there are co-morbid disorders and medical problems related to Sotos syndrome, other treatments may be necessary. Your child’s medical team will monitor and advise if additional screenings may be necessary.


As with many disorders, there are always brands and individuals touting the next “cure.” At this time, there is no cure and the best treatments/supplements/medication are those advised by your child’s doctor.

A special diet isn’t required for Malan syndrome, but it’s important that all children have a well-balanced and healthy diet.

Anxiety & Sleep

Anxiety causes sleeping problems, and research suggests sleep deprivation can cause an anxiety disorder. It is a vicious cycle for anyone to cope with, especially children.

Having a set bedtime routine and sleep schedule can go a long way to help. Make sure to create a routine that works well for your child and can be easily kept. This article on getting quality sleep for children is also a great resource.


Children with disabilities are more prone to bullying. Reports show that one out of every five students reports being bullied in some form by the time they reach eighteen.

If you notice that your school-aged child has become more anxious, depressed, or behaving differently, bullying may be the culprit. If your child is unable to inform you of possible bullying, make sure to touch base with their teacher.
