What is the official name of the SKIV2L gene?

The official name of this gene is “Ski2 like RNA helicase.”

SKIV2L is the gene's official symbol. The SKIV2L gene is also known by other names, listed below.

What is the normal function of the SKIV2L gene?

The SKIV2L gene provides instructions for making a protein whose function has not been confirmed. Based on its similarity to a protein in other organisms, researchers speculate that the SKIV2L protein acts as part of a group of proteins called the SKI complex. This complex is thought to be necessary for the function of another large protein complex known as the cytosolic exosome. Within cells, the cytosolic exosome helps to recognize and break down excess or abnormal messenger RNA (mRNA) molecules. mRNA is a chemical cousin of DNA that serves as the genetic blueprint for protein production. Studies suggest that the cytosolic exosome's role in getting rid of excess and abnormal mRNA is important for cell growth.

How are changes in the SKIV2L gene related to health conditions?

trichohepatoenteric syndrome - caused by mutations in the SKIV2L gene

At least nine mutations in the SKIV2L gene have been found to cause trichohepatoenteric syndrome, a rare condition that affects many parts of the body. Its major signs and symptoms include chronic diarrhea starting in infancy, hair abnormalities, distinctive facial features, and liver disease. Mutations in this gene likely eliminate the function of the SKIV2L protein. Researchers hypothesize that a loss of this protein's function impairs the activity of the SKI complex and the cytosolic exosome. However, it is unknown how these changes could lead to chronic diarrhea and the other features of trichohepatoenteric syndrome.

Where is the SKIV2L gene located?

Cytogenetic Location: 6p21

Molecular Location on chromosome 6: base pairs 31,958,804 to 31,969,755

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The SKIV2L gene is located on the short (p) arm of chromosome 6 at position 21.

The SKIV2L gene is located on the short (p) arm of chromosome 6 at position 21.

More precisely, the SKIV2L gene is located from base pair 31,958,804 to base pair 31,969,755 on chromosome 6.
