Catgut suture Although the name implies the usage of guts of cats, there is no record of feline guts being used for this purpose. The word catgut is derived from the term kitgut or kitstring (the string used on a kit, or fiddle). Misinterpretation of the word kit as referring to a young cat led to the use of the term catgut. Perhaps another possible explanation of the name is the combination of the words cattle and gut.

Genetic Abnormalities Involved in PKU: A Guide to Phenylketonuria slide 2 of 5. Phenylketonuria (PKU) Genetics: Mutation of the PAH Gene Phenylketonuria is caused by a mutation of the phenylalanine hydroxylase (PAH) gene which is found in the q arm of chromosome 12. The PAH gene gives specific instructions for the production of the enzyme phenylalanine hydroxylase that converts phenylalanine to tyrosine.

Gene Mutation That Causes Alzheimer's Is Found The Alzheimer's mutation, a change in a single chemical, was found on chromosome 21. Many researchers had suspected that a gene might lie on that chromosome because people with Down syndrome, who have an extra copy of chromosome 21, almost always develop Alzheimer's disease.n a leap forward in the search for a cause of Alzheimer's disease, researchers have discovered that a pinpoint mutation in a single gene can cause this progressive neurological illness.

- lactose intolerance-caused by mutations in the LCT gene. At least nine LCT gene mutations cause congenital lactase deficiency, also called congenital alactasia. In this disorder, infants are unable to break down lactose (lactose intolerance) in breast milk or formula.The LCT gene mutations change single protein building blocks (amino acids) in the lactase enzyme or result in an enzyme that is abnormally short.he mutations are believed to interfere with the function of the lactase enzyme, leading to undigested lactose in the small intestine and causing severe diarrhea. Lactose intolerance in adulthood is caused by gradually decreasing activity (expression) of the LCT gene after infancy, which occurs in most humans.

- MUTATION is caused when there is a permanent change to the sequence of a gene. Weegy: MUTATION is caused when there is a permanent change to the sequence of a gene. User: Chromosomal mutations can have a variety of effects on individuals. Down syndrome is a disorder that causes problems such as mild to moderate mental retardation and slow or stunted development. A common form of this disorder is the result of a genetic mutation that occurs when there is an extra chromosome 21.

Learning About Fragile X Syndrome Nearly all cases of fragile X syndrome are caused by a mutation in which a DNA segment, known as the CGG triplet repeat, is expanded within the FMR1 gene. Normally, this DNA segment is repeated from 5 to about 40 times. In people with fragile X syndrome, however, the CGG segment is repeated more than 200 times.

About Progeria HGPS is caused by a mutation in the gene called LMNA (pronounced “lamin-a”). The LMNA gene produces the lamin A protein which is the structural scaffolding that holds the nucleus of a cell together.The abnormal lamin A protein that causes Progeria is called progerin. Progerin makes the nucleus unstable.That cellular instability leads to the process of premature aging and disease in Progeria.he LMNA gene produces the lamin A protein which is the structural scaffolding that holds the nucleus of a cell together.

Progeria Syndrome Progeria is caused by a genetic mutation. The mutation occurs in the gene LMNA, which is responsible for producing a protein that helps maintain the structural integrity of the nucleus in cells. Without strength in the nucleus, the cell structure is weak and leads to rapid aging, or progeria.rogeria is the term for a group of disorders that cause rapid aging in children. Most common is the fatal Hutchinson-Gilford Progeria Syndrome (HGPS).
