Preferred Label : 3mc syndrome 2;
Symbol : 3MC2;
CISMeF acronym : 3MC2;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Osa syndrome; Oculo-skeletal-abdominal syndrome; Ptosis of eyelids with diastasis recti and hip dysplasia; Carnevale syndrome;
Description : The term '3MC syndrome' encompasses 4 rare autosomal recessive disorders that were
previously designated the Carnevale, Mingarelli, Malpuech, and Michels syndromes,
respectively. The main features of these syndromes are facial dysmorphism that includes
hypertelorism, blepharophimosis, blepharoptosis, and highly arched eyebrows, which
are present in 70% to 95% of cases. Cleft lip and palate, postnatal growth deficiency,
cognitive impairment, and hearing loss are also consistent findings, occurring in
40% to 68% of cases. Craniosynostosis, radioulnar synostosis, and genital and vesicorenal
anomalies occur in 20% to 30% of cases. Rare features include anterior chamber defects,
cardiac anomalies, caudal appendage, umbilical hernia (omphalocele), and diastasis
recti (summary by Rooryck et al., 2011). For a discussion of genetic heterogeneity
of 3MC syndrome, see 3MC1 (257920).;
