Genetic Testing

Snapshot: What are somatic expansions?

In a nutshell: somatic expansions are expansions of repeat DNA sequences that accumulate in cells over an individual’s lifetime. A special kind of mutation: repeat expansion mutations Some genes naturally contain repeat sequences in the DNA. For the most part, these DNA repeats are relatively short and do not cause Read More…

Snapshot: What is DNA Sequencing?

Most things about you are written in your genes: from the colour of your eyes, whether you are lactose intolerant, to if you have a higher chance of getting certain diseases. You may have heard of the popular ancestry DNA testing service that tells if you are part Chinese, part Read More…

Why Is Genetic Testing Important for Ataxia Research?

Why Is Genetic Testing Important for Ataxia Research? Genetic testing plays a pivotal role in Ataxia research. This is due to the ability of genetic testing to pinpoint specific genetic mutations associated with different forms of the condition. By identifying these genetic variations, researchers can begin to research the underlying Read More…

What Are the Benefits and Limitations of Ataxia Genetic Testing?

What Are the Benefits and Limitations of Ataxia Genetic Testing? Benefits Genetic testing offers a range of valuable benefits to individuals and society. First of all, genetic tests can tell you if you are more likely to get certain diseases and conditions, which can help doctors catch them early and Read More…

Genetic Testing for SCA27B

Genetic Testing for SCA27B SCA27B, one of the newest identified forms of Hereditary Ataxia, is anticipated to be a highly prevalent type of Ataxia. Currently, there are limited options to receive a CLIA-certified genetic test for SCA27B. This article has information about how to access SCA27B testing in the United Read More…

Snapshot: What is a Genome-Wide Association Study (GWAS)?

A genome is a person’s complete set of DNA which provides the instructions to make and maintain their body’s functions. Throughout the entire genome, there are genetic differences between individuals known as single nucleotide polymorphisms or SNPs (pronounced “snips”). These variations may be unique or may occur in many people. Read More…

How Can Genetic Testing Help Me in Managing my Ataxia Condition?

How can genetic testing help me in managing my Ataxia condition? As the adage goes, knowledge is power. Knowledge gained through genetic testing can be difficult to process. Many people can be hesitant to have genetic testing done. They may not be sure how they will process this knowledge.    At the Read More…

Snapshot: What is a Gene?

A gene is the basic physical unitof heredity. Every living cell contains genetic information that determines an organism’s development, form, and function. This genetic information is encoded by two macromolecules: DNA and RNA. DNA consists of two strands of phosphate and sugar molecules connected by pairs of nitrogenous bases to Read More…

Snapshot: What does dominant ataxia mean?

Ataxias can occur due to a multitude of reasons. One way a patient might acquire ataxia is from an accident or an injury – not as a result of genetics. On the other hand, a patient could also inherit a specific mutation (a genetic defect, in other words) from one Read More…

Snapshot: What are single nucleotide polymorphisms (SNPs)?

It’s in our DNA If you were to unravel the tightly wound packages of our genome known as chromosomes, you would find long strings of DNA. The strings are made up of only four different building blocks, compounds abbreviated as adenine (A), thymine (T), guanine (G) and cytosine (C). Picture Read More…
