Summaries for 3mc Syndrome 2

OMIM : 57 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). (265050)

MalaCards based summary : 3mc Syndrome 2, also known as ptosis of eyelids with diastasis recti and hip dysplasia, is related to 3mc syndrome and alopecia-intellectual disability syndrome, and has symptoms including torticollis An important gene associated with 3mc Syndrome 2 is COLEC11 (Collectin Subfamily Member 11). Affiliated tissues include kidney, liver and bone, and related phenotypes are hypertelorism and ptosis

Disease Ontology : 12 A 3MC syndrome that has material basis in homozygous mutation in the COLEC11 gene on chromosome 2p25.

UniProtKB/Swiss-Prot : 75 3MC syndrome 2: A form of 3MC syndrome, an autosomal recessive disorder characterized by facial dysmorphism, craniosynostosis, learning disability, and genital, limb and vesicorenal anomalies. Facial features include hypertelorism, blepharophimosis, blepharoptosis and highly arched eyebrows, cleft lip and/or palate. The term 3MC syndrome includes Carnevale, Mingarelli, Malpuech, and Michels syndromes.
