Genetic Testing

Individuals at risk for Huntington’s disease (HD) have the option of undergoing genetic testing, which detects the presence or absence of the genetic sequence that causes HD. The decision of whether or not to undergo genetic testing is intensely personal, with many factors to consider. This chapter will provide scientific background information regarding genetic testing for Huntington’s disease

An Introduction to DNA and Chromosomes (Text and Audio)

Listen to this article in mp3 format here: An Introduction to DNA and Chromosomes Let’s start with the basics of genetics. The word “genome” refers to an organism’s complete set of DNA. The fundamental building block of our genome is the molecule known as DNA. You’ve no doubt heard of DNA many times before – in […]

Huntingtin Protein and Protein Aggregation

What causes the onset of HD? Current research shows that there is an abundance of information to be learned regarding the genetic origins of HD. Let’s trace HD’s beginnings from the molecular level, exploring the relationships between a gene, a protein, aggregation “clumps,” neural cell death, and the disease itself.

All About Mutations

With their sword-wielding, karate-chopping, and pizza-eating ways, the Teenage Mutant Ninja Turtles swept American children by storm in the early 1990s. Unfortunately, though they did get kids to sit still for 30 minutes each day, the turtles also contributed to a widely held public misconception about what it means to have a mutation. From watching […]

Population Genetics and Huntington’s Disease

Listen to this article in mp3 format: Population Genetics and Huntington’s Disease Have you ever wondered where Huntington’s disease originated? Or why it’s predominantly found among Europeans and those of European descent? Population genetics, the study of the genetic makeup of populations and of changes over time in that makeup, attempts to answer such questions. In […]

An Introduction to Proteins

Proteins are very important molecules to all forms of life. They are one of four of life’s basic building blocks; the other three are carbohydrates (sugars), lipids (fats), and nucleic acids (DNA and RNA).
