What is the official name of the COLEC11 gene?

The official name of this gene is “collectin subfamily member 11.”

COLEC11 is the gene's official symbol. The COLEC11 gene is also known by other names, listed below.

What is the normal function of the COLEC11 gene?

The COLEC11 gene provides instructions for making a protein called CL-K1. This protein is involved in a series of reactions called the lectin complement pathway, which is thought to help direct the movement (migration) of cells during early development before birth to form the organs and systems of the body. The lectin complement pathway appears to be particularly important in directing the migration of neural crest cells, which give rise to various tissues including many tissues in the face and skull, glands that produce hormones (endocrine glands), and portions of the nervous system. After birth, the lectin complement pathway is involved in the immune system.

Does the COLEC11 gene share characteristics with other genes?

The COLEC11 gene belongs to a family of genes called COLEC (collectins).

A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

How are changes in the COLEC11 gene related to health conditions?

3MC syndrome - caused by mutations in the COLEC11 gene: At least five COLEC11 gene mutations have been identified in people with 3MC syndrome, a disorder characterized by unusual facial features and a variety of problems affecting other tissues and organs of the body. The COLEC11 gene mutations that cause 3MC syndrome impair or eliminate the function of the CL-K1 protein, resulting in faulty control of cell migration in embryonic development and leading to the various abnormalities that occur in this disorder. Researchers suggest that the existence of parallel pathways in the immune system that can compensate for problems in the lectin complement pathway account for the absence of immune system problems in 3MC syndrome.

Where is the COLEC11 gene located?

Cytogenetic Location: 2p25.3

Molecular Location on chromosome 2: base pairs 3,594,832 to 3,644,644

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI

)

The COLEC11 gene is located on the short (p) arm of chromosome 2 at position 25.3.

More precisely, the COLEC11 gene is located from base pair 3,594,832 to base pair 3,644,644 on chromosome 2.
