A SLC20A2 gene provides instructions for making a protein called sodium-dependent phosphate transporter 2 (PiT-2). This protein is highly active in nerve cells (neurons) in the brain. It plays a major role in regulating the levels of a molecule called phosphate in cells (phosphate homeostasis). Specifically, the PiT-2 protein uses positively charged sodium atoms (ions) to transport phosphate in out and of cell membranes. Phosphate is needed for many cellular functions including the breakdown of substances (metabolic processes), signaling between cells, and the production of DNA building blocks (nucleic acids) and fats.

Doença renal policística
If symptoms and problems develop, they usually start in adulthood. Doença renal policística autossômica recessiva (ARPKD) This is a rare condition which affects about 1 in 20,000 people. Problems typically develop soon after birth. Although people with PKD often develop kidney failure (end-stage kidney disease) between ages 55 to 65 years, some.

Distrofia muscular de Duchenne
The genes have been copied. Genes are found on 'chromosomes', rather like houses on a street. The DMD gene is located on a chromosome called the X chromosome. Boys have one X chromosome and one Y chromosome; girls have two X chromosomes. DMD is inherited in a pattern called 'X-linked inheritance'. The DMD gene is 'carried' by women but does not.

Esferocitose hereditária
Hereditary spherocytosis (HS) é an inherited condition of red blood cells. The disease can be mild and go unrecognised in some people. In others there may be severe anaemia requiring regular blood transfusions. Some people with hereditary spherocytosis may be offered surgery to remove their spleen. This usually helps the condition, but increases.
