    • Some Facts About Genetics and Huntington’s

    Everyone has two copies of the Huntington's gene - one inherited from each parent For those who don't know, a gene is a piece of hereditary information which is present in every cell of the body and tells cells what to do and when to do it. Genes are usually attached to a chromosome (a strand of DNA containing many different genes). Each human cell...

    CAG is a DNA code. DNA (Deoxyribonucleic acid) is a self-replicating material that is present in nearly all living organisms. It is the carrier of genetic information. The four chemicals that make up DNA are A (Adenine), T (Thymine), C (Cystostine) and G (Guanine). The code for the Huntington’s gene contains three of these chemicals C, A and G whic...

  4. Huntington's disease is inherited in an autosomal dominant fashion. The probability of each offspring inheriting an affected gene is 50%. Inheritance is independent of sex, and the phenotype does not skip generations.

  5. Jul 19, 2024 · Huntington's disease (HD) is an inherited disorder that causes nerve cells (neurons) in parts of the brain to gradually break down and die. The disease attacks areas of the brain that help to control voluntary (intentional) movement, as well as other areas.

  6. Jun 3, 2024 · Huntington’s disease is a condition that damages nerve cells in the brain causing them to stop working properly. It’s passed on (inherited) from a person’s parents. The damage to the brain gets worse over time. It can affect movement, cognition (perception, awareness, thinking, judgement) and mental health. Symptoms of Huntington’s disease.

  7. Apr 25, 2024 · Huntington's disease is caused by a difference in a single gene that's passed down from a parent. Huntington's disease follows an autosomal dominant inheritance pattern. This means that a person needs only one copy of the nontypical gene to develop the disorder.
