The LYST gene (also known as CHS1 ) provides instructions for making a protein known as the lysosomal trafficking regulator. Researchers believe that this protein plays a role in the transport (trafficking) of materials into structures called lysosom READ MORE

The LZTR1 gene provides instructions for making a protein whose exact function is unknown. The LZTR1 protein is made in cells throughout the body. Within cells, it is found in the Golgi apparatus, which is a structure in which newly produced proteins READ MORE

The MAGT1 gene provides instructions for making a protein called a magnesium transporter, which moves charged atoms (ions) of magnesium (Mg 2+ ) into certain immune system cells called T cells. T cells recognize foreign invaders, such as viruses, bac READ MORE

The MAN2B1 gene provides instructions for making the enzyme alpha-mannosidase. This enzyme works in the lysosomes, which are compartments that digest and recycle materials in the cell. Within lysosomes, the enzyme helps break down complexes of sugar READ MORE

The MANBA gene provides instructions for making the enzyme beta-mannosidase. This enzyme works in the lysosomes, which are compartments that digest and recycle materials in the cell. Within lysosomes, the enzyme helps break down complexes of sugar mo READ MORE

The MAOA gene provides instructions for making an enzyme called monoamine oxidase A. This enzyme is part of a family of enzymes that break down molecules called monoamines through a chemical reaction known as oxidation. Among the monoamines broken do READ MORE

The MAP2K1 gene provides instructions for making a protein known as MEK1 protein kinase. This protein is part of a signaling pathway called the RAS/MAPK pathway, which transmits chemical signals from outside the cell to the cell's nucleus. RAS/MAPK s READ MORE

The MAP2K2 gene provides instructions for making a protein known as MEK2 protein kinase. This protein is part of a signaling pathway called the RAS/MAPK pathway, which transmits chemical signals from outside the cell to the cell's nucleus. RAS/MAPK s READ MORE

The MAP3K1 gene provides instructions for making a protein that helps regulate signaling pathways that control various processes in the body, including the processes of determining sex characteristics before birth. The MAP3K1 protein attaches (binds) READ MORE

The MAPT gene provides instructions for making a protein called tau. This protein is found throughout the nervous system, including in nerve cells (neurons) in the brain. It is involved in assembling and stabilizing microtubules, which are rigid, hol READ MORE

The MASP1 gene provides instructions for making proteins that are involved in a series of steps called the lectin complement pathway. This pathway is thought to help direct the movement (migration) of cells during development before birth to form the READ MORE

The MAT1A gene provides instructions for producing the enzyme methionine adenosyltransferase. The enzyme is produced from the MAT1A gene in two forms, designated MATI and MATII. MATI is made up of four identical protein subunits, which is known as a READ MORE
