What does the COL1A1 gene do?
The COL1A1 gene provides instructions for making part of a large molecule called type I collagen. Collagens are a family of proteins that strengthen and support many tissues in the body, including cartilage, bone, tendon, skin, and the white part of the eye (the sclera).
Where is the COL1A1 gene located?
Gene. The COL1A1 gene is located on the long (q) arm of chromosome 17 between positions 21.3 and 22.1, from base pair 50183289 to base pair 50201632.
What is COL1A1 and COL1A2 genes?
Most patients with a clinical diagnosis of OI type I-IV have a mutation in the COL1A1 or COL1A2 genes which encode the two alpha chains of type I collagen, the major component of the bone matrix.
What is the difference between COL1A1 and COL1A2?
COL1A1 gene mutations are more pathogenic and cause OI more often than COL1A2 gene mutations. One third of glycine (Gly) substitutions in the COL1A1 gene are lethal, whereas only 1/5 of Gly pathogenic variants in the COL1A2 gene are fatal [5].
Does Type 1 collagen help bones?
Type I collagen is one of the most abundant molecules in the body, and it is particularly important in bone, skin, and connective tissue.
What happens if collagen is mutated?
Mutations in Type I Collagen That Cause Osteogenesis Imperfecta. Osteogenesis imperfecta (brittle-bone disease) is characterized by a fragility of bone that is apparent early in life. Severe forms produce death in utero because of the extreme fragility of bone, skin, ligaments, and other tissues rich in Type I collagen …

What chromosome is COL1A1 and COL1A2 on?
COL1A1 gene, containing 51 exons, is located on chromosome 17 and COL1A2 gene, containing 52 exons, is on chromosome 7.
What is the difference between collagen type 1 2 and 3?
The main difference between collagen 1 2 and 3 is that collagen 1 is most abundant in bones, tendons, ligaments, and in the skin while collagen 2 occurs in hyaline and articular cartilages and collagen 3 is the main component of reticular fibers which make a supporting mesh in soft tissues and organs.
Do you need all 5 types of collagen?
While 28 different types of collagen do exist—differentiated by where in the body it’s sourced and its amino acid structure—Dr. Bitz explains that they’re all still the same protein. “When you ingest collagen, you’re rebuilding all of your own collagen in the body, not just Type 1 or 3, but every type,” he explains.
Is collagen vascular disease curable?
The outlook for collagen vascular disease varies from person to person, and it depends on their specific disease. However, they do have one thing in common: All autoimmune diseases are chronic conditions. They have no cure, and you must manage them throughout your life.
How do you reduce collagen in your body?
Besides time, three main things will lower your collagen levels: sunlight, smoking, and sugar. Too much exposure to ultraviolet light makes its fibers unravel. This can lead to sun damage, such as wrinkles. Many of the chemicals in cigarette smoke can damage it, which can make skin sag and wrinkle.
