What is the official name of the UMOD gene?
The official name of this gene is “uromodulin.”
UMOD is the gene's official symbol. The UMOD gene is also known by other names, listed below.
What is the normal function of the UMOD gene?
The UMOD gene provides instructions for making a protein called uromodulin. This protein is produced by the kidneys and then excreted from the body in urine. The function of uromodulin remains unclear, although it is known to be the most abundant protein in the urine of healthy individuals. Researchers have suggested that uromodulin may protect against urinary tract infections. It may also help control the amount of water in urine.
How are changes in the UMOD gene related to health conditions?
- uromodulin-associated kidney disease - caused by mutations in the UMOD gene
More than 40 mutations in the UMOD gene have been found to cause uromodulin-associated kidney disease. Most of these mutations change single protein building blocks (amino acids) used to make uromodulin. These mutations alter the structure of the protein, preventing its release from kidney cells. Abnormal buildup of uromodulin may trigger the self-destruction (apoptosis) of cells in the kidneys, causing kidney disease.
Where is the UMOD gene located?
Cytogenetic Location: 16p12.3
Molecular Location on chromosome 16: base pairs 20,333,050 to 20,356,300
The UMOD gene is located on the short (p) arm of chromosome 16 at position 12.3.
More precisely, the UMOD gene is located from base pair 20,333,050 to base pair 20,356,300 on chromosome 16.
