Clinical features
Mutations in the C12orf57 gene cause Temtamy syndrome, which is characterized by developmental delay and intellectual disability, epilepsy, reduced muscle tone, small eyes, defects in the choroid, retina, or iris of the eye, and abnormal facial appearance.

Largely unknown due to limited data.

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.
