What it is down syndrome? Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms and functions as it grows during pregnancy and after birth. Typically, a baby is born with 46 chromosomes.
What is Down syndrome and what causes it? Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21. This extra genetic material causes the developmental changes and physical features of Down syndrome.
How does Down syndrome affect a person? An individual with Down syndrome inherits all or part of an extra copy of Chromosome 21. Symptoms associated with the syndrome include mental retardation, distinctive facial characteristics, and increased risk for heart defects and digestive problems, which can range from mild to severe.
Why is it called Down syndrome? Down syndrome is named after the English doctor, John Langdon Down, who was the first to categorize the common features of people with the condition. 2. Dr. Jerome Lejeune discovered Down syndrome is a genetic disorder whereby a person has three copies of chromosome 21 instead of two.

Can a down syndrome person reproduce?
Affected individuals rarely reproduce. About 15-30% of females with trisomy 21 are fertile and have up to a 50% risk of having child also affected with trisomy 21. Infertility in males has been attributed to defective spermatogenesis, but ignorance of the sexual act may be one of the contributing factors.
What to rule out when looking at cyclic vomiting syndrome?
Cyclic vomiting syndrome can be difficult to diagnose. There’s no specific test to confirm the diagnosis, and vomiting is a sign of many conditions that must be ruled out first. The doctor will start by asking about your child’s or your medical history and conducting a physical exam.
What causes trisomy syndrome?
Most cases of trisomy 18 are not inherited, but occur as random events during the formation of eggs and sperm. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 18.
How is inflammation involved with metabolic syndrome?
Chronic inflammation may represent a triggering factor in the origin of the metabolic syndrome: stimuli such as overnutrition, physical inactivity, and ageing would result in cytokine hypersecretion and eventually lead to insulin resistance and diabetes in genetically or metabolically predisposed individuals.
