Are Telemore DNA Tests Reliable?

Genealogy, science
What are Telomeres? Telomeres are distinctive structures, regionized in DNA strands which are located at each end. They are caps to prevent the chromosome from deteriorating, somewhat like the plastic shells of a shoelace. They have a repetitive, short DNA sequence and are many kilobases in length. The Telomeres also prevent fusing with neighbouring chromosomes. Telomeres derives from the two Greek words “telos” which means “end” and ”meros” which means “part”. The sequence in human Telomeres is TTAGGG, which is repeated around 2,500 times. There are 194 Telomeres in a human cell, 4 for each of the 46 chromosomes. What are Telomere tests As cells age, its Telomeres gradually become shorter. The average cell will divide around 60 times before it dies. As the cell divides, the Telomeres of course…

Is your privacy protected when you do a DNA test?

Is your privacy protected when you do a DNA test?

Privacy
You may think that the Privacy Policy of your favorite DNA testing company protects you, your identity, and your personally identifiable information. But, that is simply not the case. Even though most DNA testing companies de-personalize your data, the nature of genetic data itself stores personally-identifiable information. So, just because your name is not on the sample, there are still methods which can be used to identify your genetic code. Further, genetic testing companies are not covered under the Health Insurance Portability and Accountability Act (HIPAA). This act typically enforces the rule that doctors and health insurance agencies cannot share your personal medical records with first removing all personally identifiable information.  And, while the Genetic Information Nondiscrimination Act (GINA) does protect you from being excluded from Medicare based on your…

DNA Data Testing: How Accurate and Useful?

DNA Data Testing: How Accurate and Useful?

science
DNA testing kits are an amazing piece of technology. Just imagine, in 2003 the Human Genome Project was completed. It took scientists BILLIONS of dollars and an entire DECADE to complete. Today, you can have important pieces of your DNA tested for less than $100, or get your entire genome sequenced for less than $1000. Not only this, but you can get the results from the comfort of your home, after sending in a simple DNA sample from your cheek cells. Companies like 23andMe, Ancestry, and Veritas Genetics have sprung up to bring the power of DNA testing to the masses. These companies offer a number of different tests, ranging from what your genetics can tell you about your genealogy to the various disease risks you may carry due to…

AncestryDNA Vs. 23andMe: A Comparison

Comparisons
When you compare AncestryDNA and 23andMe you will find that the companies are both excellent at what they do. However, they provide slightly different services which are marketed to different types of users. Ancestry focuses on genealogy testing and analysis, which a whole suite of tools for building and researching your family tree. 23andMe combines a simpler version of ancestry testing with genetic health testing to provide a larger set of information from your genetic material. Both companies excel in certain areas, while both companies also have weaknesses.

At-Home DNA Tests: Taking Action on Your Results

Genealogy
At home DNA tests can provide a large wealth of information about your genetics. Many companies now offer these tests, with a wide variety of results and information being analyzed. Some tests focus solely on ancestry, while others analyze aspects of your genes related to health, disease, fitness, or nutrition. While all of these tests use similar methods of correlating DNA data to various outcomes, not all tests are extremely useful. To get the most out of your DNA test kit, you need to understand what results you are getting, how accurate and predictive those results are, and what you can do in spite of your genetics. Below is a thorough review of many different types of genetic tests, the results you can expect, and what you can do to…

23andMe Polygenic Risk Scores

23andMe Polygenic Risk Scores

science
When it comes to innovating genetic testing, 23andMe is always at the forefront of science. Not only were they one of the first companies on the genetic testing scene, but they were one of the first to get their breast-cancer screening test approved by the FDA. The company is partially owned by Google Ventures, Google’s start-up investment wing. This gives 23andMe a technological edge over other companies, and they are often the first on the market with a new offering. Recently, 23andMe started offering a polygenic risk score for diabetes, offering another thing to differentiate it in the 23andMe vs Ancestry battle and marking it as a top leader in both ancestry testing and health testing.

The Truth about Genetics and Disease: Is it Nature, or Nurture?

The Truth about Genetics and Disease: Is it Nature, or Nurture?

science
The FDA recently approved 23andMe’s genetic test which screens for breast cancer. The move was heralded as a great advancement in the field of direct-to-consumer genetic testing. Many people purchased the test, hoping it would reveal whether or not they would get breast cancer. However, in its approval, the FDA also mentioned some serious limitations of the test. For one, it only tests for 3 of thousands of known mutations. If any other spot in the BRCA gene is mutated, the test would show negative when you actually do have a higher risk. But more importantly than that, the BRCA mutations they screen for are “rarely found” in the general population. Even those of Ashkenazi Jewish descent, who experience a higher rate of the mutation, only find it in around…

Home DNA Paternity Test

Genealogy, science
Can Direct-to-Consumer Genetics Tests Provide Accurate Results? First, How Does Paternity Testing Work? Paternity testing, like other forms of familial testing (sibling, maternal, etc.) is a relatively straightforward practice. Other forms of DNA analysis rely on understanding the genes involved and their relationship with disease. In paternity testing, scientists are simply checking to see if the DNA matches in various locations. In this article we will focus on home DNA paternity tests. To understand how this process can identify someone as a direct family member, you must understand a little bit about genetics. A human starts as two different cells, the sperm and the egg. Inside of these cells is exactly half of the DNA necessary to create a human. Both cells contain 23 chromosomes, or parts of DNA. Half Mom,…
