यह MTR gene provides instructions for making an enzyme called methionine synthase. This enzyme plays a role in processing amino acids, the building blocks of proteins. Specifically, methionine synthase carries out a chemical reaction that converts the amino acid homocysteine to another amino acid called methionine. The body uses methionine to make proteins and other important compounds. To function properly, methionine synthase requires methylcobalamin (a form of vitamin B12) and another enzyme called methionine synthase reductase, which is produced from the MTRR gene.

Polycystic kidney disease (PKD) causes many fluid-filled sacs (cysts) to develop in the kidneys. The most common type of PKD is an inherited condition called autosomal dominant polycystic kidney disease (ADPKD). With ADPKD, problems commonly do not develop until the age of 30-50, with some people never developing any problems. About half of ADPKD.
