The CLCN2 gene belongs to the CLC family of genes, which provide instructions for making chloride channels. These channels, which transport negatively charged chlorine atoms (chloride ions), play a key role in a cell's ability to generate and transmit electrical signals. Some chloride channels regulate the flow of chloride ions across cell membranes, while others transport chloride ions within cells.

The CLCN2 gene belongs to the CLC family of genes, which provide instructions for making chloride channels. These channels, which transport negatively charged chlorine atoms (chloride ions), play a key role in a cell's ability to generate and transmit electrical signals. Some chloride channels regulate the flow of chloride ions across cell membranes, while others transport chloride ions within cells.
The CLCN2 gene provides instructions for making a chloride channel called ClC-2. These channels are embedded within the outer membrane of most cells, and they transport chloride ions in and out of cells. The channel's function is thought to be particularly important in nerve cells (neurons) in the brain. The ClC-2 channel regulates the size (volume) of neurons by playing a role in the intake and release of water as well as maintaining a normal balance of ions in cells.

Kidney cancer
This is sometimes called renal adenocarcinoma or renal cell carcinoma or hypernephroma. Renal cell cancer This type of cancer develops from a cell in a kidney tubule, which becomes cancerous (malignant). The cancer grows and forms into a tumour within the kidney. As the tumour grows: The affected kidney tends to become larger. In time the tumour.

Burns and scalds
Burns caused b... For electrical burns - disconnect the victim from the source of electricity before attempting first aid. If you cannot switch off the electricity: If the person has been injured by a low-voltage source (220-240 volts, domestic electricity supply) then remove the person from the electrical source, using a non-conductive material.

Nasal polyps
Side-effects of topical steroid medications These include nasal irritation, sore throat and nosebleeds. About 1 in 10 people using these medications will experience one of these symptoms. Some people are sensitive to a preservative called benzalkonium chloride, found in all all nasal steroid treatments (drops and sprays), except for Flixonase.
