What is the official name of the MKKS gene?
The official name of this gene is “McKusick-Kaufman syndrome.”
MKKS is the gene's official symbol. The MKKS gene is also known by other names, listed below.

What is the normal function of the MKKS gene?
The MKKS gene provides instructions for making a protein that plays an important role in the formation of the limbs, heart, and reproductive system. The structure of this protein suggests that it may act as a chaperonin, which is a protein that helps fold other proteins. Proteins must be folded into the correct 3-dimensional shape to perform their usual functions in the body. Abnormally folded proteins can also interfere with the functions of normal proteins.
Although the structure of the MKKS protein is similar to that of a chaperonin, some studies have suggested that protein folding may not be this protein's primary function. Within cells, the MKKS protein is associated with structures called centrosomes. Centrosomes play a role in cell division and the assembly of microtubules, which are proteins that transport materials in cells and help the cell maintain its shape. Researchers speculate that the MKKS protein may be involved in transporting other proteins within the cell.
How are changes in the MKKS gene related to health conditions?
Genetics Home Reference provides information about Bardet-Biedl syndrome, which is also associated with changes in the MKKS gene.
Where is the MKKS gene located?
Cytogenetic Location: 20p12
Molecular Location on chromosome 20: base pairs 10,404,780 to 10,434,239
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The MKKS gene is located on the short (p) arm of chromosome 20 at position 12.
More precisely, the MKKS gene is located from base pair 10,404,780 to base pair 10,434,239 on chromosome 20.
