Any 3MC syndrome in which the cause of the disease is a mutation in the COLEC10 gene.
Features include very common findings: Blepharophimosis; and common findings: Epicanthus inversus, Diastasis recti, Highly arched eyebrow, and Cleft palate and others. 27 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Head and neck | 3 | Cleft palate, Cleft upper lip, Tessier cleft |
COLEC10 encodes collectin subfamily member 10 (277 aa). Lectin that binds to various sugars: galactose > mannose = fucose > N-acetylglucosamine > N-acetylgalactosamine. Acts as a chemoattractant, probably involved in the regulation of cell migration Highest expression in Liver (14.3 TPM) and Lung (0.9 TPM).
3MC syndrome 3 is associated with mutations in the COLEC10 gene on chromosome 8.
The COLEC10 protein participates in Lectin pathway of complement activation pathway.
COLEC10 is classified as a druggable target (Druggable Genome and External Side Of Plasma Membrane categories) with score 0.9.
Genetic testing for COLEC10 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 1 very common feature, 8 common features.
No clinical trials have been registered for 3MC syndrome 3.
3 publications have been identified in PubMed for 3MC syndrome 3. Research spans Case Report / Case Series (67%) and Basic Science / Preclinical (33%).

A new treatment for children aged 2 or older with sickle cell disease has been approved by the U.S. Food & Drug Administration. In a press release on Wednesday, the FDA announced it had approved Casgevy, the first gene therapy for children with sickle cell disease. (NewsNation) — A new treatment for children aged 2 or older with sickle cell disease has been approved by the Food & Drug Administration (FDA). In a Wednesday news release, the FDA announced it had approved Casgevy, the first gene therapy for children with the disease. “Casgevy is a gene therapy consisting of the patient’s own (autologous) hematopoietic (blood) stem cells, administered as a one-time single dose for intravenous infusion,” the release noted. “Pediatric patients as young as 2 years of age can now access a critical additional treatment option to treat these debilitating, life-threatening diseases,” Karim Mikhail, the acting director of the Center for Biologics Evaluation and Research, wrote. “These disorders carry a heavy burden for children and their families, affecting growth, development, and long-term health in profound ways,” Megha Kaushal, acting deputy director of the Office of Therapeutic Products in CBER, said in the release.
