- Edwards syndrome (also known as trisomy 18 [ T18 ]) is a chromosomal abnormality caused by the presence of all, or part of, an extra 18th chromosome. This genetic condition almost always results from nondisjunction during meiosis.t is the second-most common autosomal trisomy, after Down syndrome, that carries to term. Edwards syndrome occurs in around one in 6,000 live births, and around 80% of those affected are female. The majority of fetuses with the syndrome die before birth. The incidence increases as the mother's age increases.

Angelman syndrome Angelman syndrome is a genetic disorder that affects the nervous system and causes severe physical and intellectual disability. It's relatively rare, occurring in around 1 in 16,000 people.Typical characteristics of Angelman syndrome include: 1  delayed development (usually noticeable from 6-12 months of age).n most cases of Angelman syndrome (about 70%), the child's maternal copy of the UBE3A gene is missing, which means there's no active copy of the UBE3A gene in the child's brain.

Pearson syndrome Pearson Syndrome is a very rare mitochondrial disorder that is characterized by health conditions such as sideroblastic anemia, liver disease, and exocrine pancreas deficiency.t is usually fatal in infancy. The few patients who survive into adulthood often develop symptoms of Kearns-Sayre syndrome. It is caused by a deletion in mitochondrial DNA. Pearson syndrome is very rare, less than hundred cases have been reported in medical literature worldwide.

Cancer and ABO Blood Group My observation has been that blood type A women have a generalized tendency to worse outcomes and a more rapid progression with this cancer. Research indicates that blood type A women are over-represented among breast cancer patients, and that this trend occurs even among women thought to be at low risk for cancer.

Dimethyltryptamine (DMT) DMT can be found in many species of plants. Genera such as acacia, anadenanthera, mimosa, piptadenia, and virola are some examples. DMT is also produced in the human pineal gland, a small reddish-gray gland (about the size of a pea) near the center of the brain.One of the functions of the pineal gland is the production of melatonin. The pineal gland and melatonin help regulate sleep-wake cycles (circadian rhythms).enera such as acacia, anadenanthera, mimosa, piptadenia, and virola are some examples.

Hurler syndrome What is Hurler syndrome? Hurler syndrome is a disease you’re born with that affects metabolism. Metabolism is how the body breaks down food into energy. In Hurler syndrome, the body is missing an important protein (enzyme) to break down a sugary substance in the body. When the sugary substance isn’t broken down, it builds up and causes problems. It can damage the brain, heart and other organs.
