The PYCR1 gene provides instructions for making a protein that is located in the energy-producing structures of cells, called mitochondria. The PYCR1 protein appears to be important for the function of mitochondria and it helps in the formation (synthesis) of the protein building block (amino acid) proline.
Normal function
The PYCR1 gene provides instructions for making a protein that is located in the energy-producing structures of cells, called mitochondria. The PYCR1 protein appears to be important for the function of mitochondria and it helps in the formation (synthesis) of the protein building block (amino acid) proline.
The formation of proline is a multi-step process that converts the amino acid glutamate to the amino acid proline. The PYCR1 protein carries out the last step in this process by turning pyrroline-5-carboxylate into proline. The conversion between proline and glutamate is important in maintaining a supply of the amino acids needed for protein production, and for energy transfer within the cell.

Doença renal policística
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.

Genes BRCA
There are a few known gene changes (mutations) that can increase the risk of certain cancers, and tests available for some of them, including BRCA1 e BRCA2 gene mutations.
