Michels syndrome

Overview

Type of disease: Rare conditions

Michels syndrome is an extremely rare disorder characterized by the eyelid triad of blepharophimosis (a narrowing of the eye opening), blepharoptosis and epicanthus inversus (an upward fold of the skin of the lower eyelid near the inner corner of the eye), skeletal defects including craniosynostosis, cranial asymmetry, abnormality of the occipital bone (at the base of the skull), and radioulnar synostosis, cleft lip and palate, and mental deficiency. Only 10 cases have been reported in the medical literature. While the underlying cause of this condition remains unknown, it is believed to be transmitted as an autosomal recessive trait.  

Based on phenotypic overlap and autosomal recessive inheritance, some researchers have suggested that Michels, Malpuech, Carnevale and Mingarelli syndromes represent a spectrum and should be referred to a 3MC syndrome (for Malpuech-Michels-Mingarelli-Carnevale).
