La SALL1 gene is part of a group of related genes that provide instructions for making proteins involved in the formation of tissues and organs before birth. These proteins are transcription factors, which means they attach (bind) to specific regions of DNA and help control the activity of particular genes.
Normal function
La SALL1 gene is part of a group of related genes that provide instructions for making proteins involved in the formation of tissues and organs before birth. These proteins are transcription factors, which means they attach (bind) to specific regions of DNA and help control the activity of particular genes.
The SALL1 protein helps turn off (repress) gene activity by interacting with other proteins that alter how tightly regions of DNA are packaged. This process, known as chromatin remodeling, is one way gene expression is regulated during development; typically, when DNA is tightly packed, gene expression is lower than when DNA is loosely packed. By controlling gene activity, the SALL1 protein plays an important role in development of the hands (particularly the thumbs), ears, anus, kidneys, and other parts of the body before birth.

Hémophilie
Hémophilie is a rare saignement disorder that affects your ability to make a clot. The blood contains substances called clotting factors that work with platelets to form a clot.
