What is the official name of the BCHE gene?The official name of this gene is “butyrylcholinesterase.” BCHE is the gene's official symbol. The BCHE gene is also known by other names, listed below. Read more about gene names and symbols on the About page. What is the normal function of the BCHE gene?The BCHE gene provides instructions for making the pseudocholinesterase enzyme, also known as butyrylcholinesterase, which is produced by the liver and circulates in the blood. The pseudocholinesterase enzyme is involved in the breakdown of certain drugs, including muscle relaxant drugs called choline esters that are used during general anesthesia. These drugs are given to relax the muscles used for movement (skeletal muscles), including the muscles involved in breathing, and are often employed in emergencies when a breathing tube must be inserted quickly. Pseudocholinesterase also helps protect the body by breaking down certain toxic substances before they reach the nerves. These substances include certain pesticides, poisons that attack the nerves, and specific natural toxins including a compound called solanine found in green potato skin. It is likely that the enzyme has other functions in the body, but these functions are not well understood. Studies suggest that the enzyme may be involved in the transmission of nerve signals. How are changes in the BCHE gene related to health conditions?
Where is the BCHE gene located?Cytogenetic Location: 3q26.1-q26.2 Molecular Location on chromosome 3: base pairs 165,490,691 to 165,555,252 The BCHE gene is located on the long (q) arm of chromosome 3 between positions 26.1 and 26.2. More precisely, the BCHE gene is located from base pair 165,490,691 to base pair 165,555,252 on chromosome 3. See How do geneticists indicate the location of a gene? in the Handbook.
