Parents

Clinical features
Mutations in the METTL23 gene may cause autosomal recessive intellectual disability.

Prevalence
The prevalence is not known with less than 30 cases reported to date

Inheritance
Mutations of this gene can be passed on to the next generation in an autosomal recessive manner. This means that if both parents carry a mutation involving this gene (usually without displaying the disease), there is a greater chance that their children are going to inherit the mutations from both parents and display the disease. This is especially important to consider in consanguineous marriage, where the chance of both parents having the same mutation and passing it is greater.
