SPRED1

Reviewed February 2011

What is the official name of the SPRED1 gene?

The official name of this gene is “sprouty-related, EVH1 domain containing 1.”

SPRED1 is the gene's official symbol. The SPRED1 gene is also known by other names, listed below.

What is the normal function of the SPRED1 gene?

The SPRED1 gene provides instructions for making the Spred-1 protein, which helps control (regulate) the Ras/MAPK signaling pathway. The Ras/MAPK pathway is involved in the growth and division of cells (proliferation), the process by which cells mature to carry out specific functions (differentiation), cell movement, and the self-destruction of cells (apoptosis).

The Spred-1 protein attaches (binds) to a protein called Raf, which is part of the Ras/MAPK pathway. The binding of the Spred-1 protein blocks the activation of Raf, stopping the signaling through the remainder of the Ras/MAPK pathway.

How are changes in the SPRED1 gene related to health conditions?

Legius syndrome - caused by mutations in the SPRED1 gene

Mutations in the SPRED1 gene cause Legius syndrome, a condition characterized by multiple café-au-lait spots, which are flat patches on the skin that are darker than the surrounding area.

Several mutations have been identified throughout the SPRED1 gene. These mutations lead to a nonfunctional Spred-1 protein, usually because the mutated gene provides instructions for a shortened protein. The nonfunctional Spred-1 protein is unable to bind and block the activation of the Raf protein, which means the Ras/MAPK pathway is continuously active. It is unclear how mutations in the SPRED1 gene cause the signs and symptoms of Legius syndrome.

Where is the SPRED1 gene located?

Cytogenetic Location: 15q14

Molecular Location on chromosome 15: base pairs 38,545,051 to 38,649,449

The SPRED1 gene is located on the long (q) arm of chromosome 15 at position 14.

The SPRED1 gene is located on the long (q) arm of chromosome 15 at position 14.

More precisely, the SPRED1 gene is located from base pair 38,545,051 to base pair 38,649,449 on chromosome 15.
