Management of Knee Flexion Contracture in a Child With 3MC Syndrome Using Taylor Spatial Frame

3MC syndrome is a rare genetic disorder inherited through an autosomal recessive inheritance pattern caused by mutations in one of three genes: COLEC11, COLEC10, and MASP1. High-arched brows, ptosis, blepharophimosis, hypertelorism, cleft lip, cleft palate, developmental delay, hearing loss, abdominal wall defect, and urogenital and skeletal abnormalities are all characteristics. In previous reports, involvement of knee flexion contracture was not known to be one of the 3MC syndrome symptoms. The prevalence of 3MC syndrome is still unknown, and there have only been a few reports. We report the case of a four-year-old female with 3MC syndrome who was diagnosed with a confirmed mutation in the COLEC11 gene. We describe a method for decreasing knee flexion contracture in a reported patient that makes use of the Taylor spatial frame (TSF). Accepted results were observed because the patient has full extension, which must be maintained by the brace. According to our findings, the TSF was the safest, most accurate, stable fixator, and most efficient solution for treating knee flexion contracture, resulting in high patient and family satisfaction.

Association of Polymorphisms of MASP1/3, COLEC10, and COLEC11 Genes with 3MC Syndrome

The Malpuech, Michels, Mingarelli, Carnevale (3MC) syndrome is a rare, autosomal recessive genetic- disorder associated with mutations in the MASP1/3, COLEC1,1 or COLEC10 genes. The number of 3MC patients with known mutations in these three genes reported so far remains very small. To date, 16 mutations in MASP-1/3, 12 mutations in COLEC11 and three in COLEC10 associated with 3MC syndrome have been identified. Their products play an essential role as factors involved in the activation of complement via the lectin or alternative (MASP-3) pathways. Recent data indicate that mannose-binding lectin-associated serine protease-1 (MASP-1), MASP-3, collectin kidney-1 (collectin-11) (CL-K1), and collectin liver-1 (collectin-10) (CL-L1) also participate in the correct migration of neural crest cells (NCC) during embryogenesis. This is supported by relationships between MASP1/3, COLEC10, and COLEC11 gene mutations and the incidence of 3MC syndrome, associated with craniofacial abnormalities such as radioulnar synostosis high-arched eyebrows, cleft lip/palate, hearing loss, and ptosis.
