The HAX1 gene provides instructions for making a protein called HS-1-associated protein X-1 (HAX-1). This protein is involved in the regulation of apoptosis, which is the process by which cells self-destruct when they are damaged or no longer needed. Apoptosis is a common process that occurs throughout life. The HAX-1 protein is also thought to be involved in cell movement (migration). The HAX-1 protein is found primarily in the mitochondria, the energy-producing centers within cells.

The HAX1 gene provides instructions for making a protein called HS-1-associated protein X-1 (HAX-1).

Apoptosis is a common process that occurs throughout life. The HAX-1 protein is also thought to be involved in cell movement (migration). The HAX-1 protein is found primarily in the mitochondria, the energy-producing centers within cells.
Different versions of the HAX-1 protein can be produced from the HAX1 gene by a mechanism called alternative splicing. This mechanism produces different version of the protein by cutting and rearranging the genetic instructions in different ways. The purpose of these multiple versions of the HAX-1 protein is unclear.

Glycogen storage disorders
Glycogen storage disorders are a group of inherited diseases. They result from a problem with one of the proteins (known as enzymes) involved in the conversion of glucose to glycogen, or the breakdown of glycogen back into glucose. They mostly tend to affect your liver and muscles. Newer treatment possibilities provide hope for an improved outlook.

Genetic testing
Genetic testing is a type of medical test that identifies changes in chromosomes, genes or proteins. Genetic tests examine a person's DNA in a variety of ways to assess a person's genetic health. We all have 46 chromosomes in our cells. Genes are short sections of DNA and each chromosome contains hundreds to thousands of genes. Genes contain the.
