Causes and origins of Tourette syndrome In some cases, tics may not be inherited; these cases are identified as sporadic Tourette syndrome (also known as tourettism) because a genetic link is missing. A person with Tourette syndrome has about a 50% chance of passing the gene(s) to one of his/her children. Gender appears to have a role in the expression of the genetic vulnerability, with males more likely to express tics than females.

- But with the proper diagnosis and treatment, most kids with osteosarcoma recover. Risk for Childhood Osteosarcoma. Osteosarcoma is most often seen in teenage boys. Teens diagnosed with osteosarcoma tend to be tall for their age, suggesting that rapid bone growth may lead to the disease. Kids who have inherited one of the rare cancer syndromes also are at higher risk for osteosarcoma. These syndromes include retinoblastoma (a malignant tumor that develops in the retina, a part of the eye, usually in children younger than age 2) and Li-Fraumeni syndrome (a kind of inherited genetic mutation, or change in a person's genes).

Genetic Drift and the Founder Effect Genetic Drift and the Founder Effect. Polydactyly -- extra fingers or sometimes toes -- is one symptom of Ellis-van Creveld syndrome. Genetically inherited diseases like Ellis-van Creveld are more concentrated among the Amish because they marry within their own community, which prevents new genetic variation from entering the population.

- A variety of genetic and environmental factors likely play a role in causing Tourette syndrome. Most of these factors are unknown, and researchers are studying risk factors before and after birth that may contribute to this complex disorder.everal decades of research have shown that this is not the case. Almost all cases of Tourette syndrome probably result from a variety of genetic and environmental factors, not changes in a single gene.

Chediak-Higashi Syndrome Back to TopCauses. Chediak-Higashi syndrome is passed down through families (inherited). It is an autosomal recessive disease. This means that both parents are carriers of a non-working copy of the gene, and each parent must pass their non-working gene to the child for them to show symptoms of the disease. Defects have been found in the CHS1 (also called LYST ) gene.

None of the healthy control subjects had that mutation.

Alone we are rare. Together we are strong.â¥ Donate Today The symptoms of congenital Brown Syndrome may occur due to shortening of the tendon sheath of the superior oblique muscle or thickening of the sheath that restricts its movement. However, acquired Brown Syndrome may be the result of trauma, surgery, and/or inflammation due to another underlying disorder such as Lupus or Rheumatoid Arthritis. There are several reports in the medical literature of a few rare cases of Brown Syndrome which may be inherited as an autosomal dominant genetic trait.
