Symptoms and Signs

The most common symptoms of this disorder include widely-spaced eyes, undersized upper jaw bone, eyelid folds that are downslanting, and unusually prominent brow. Less typical symptoms include seizures, thick calvarium, small head, hypoplastic sinuses, and dilated lateral ventricles.


Coffin-Lowry syndrome is caused by gene mutations of the Ribosomal Protein S6 Kinase. The gene is situated on the X chromosome's short arm, and this produces the protein involved in signaling cells and plays a major role in central nervous system. The mutation disturbs the protein's function leading to the syndrome.
