Are you being ripped off? Correlation vs. Causation in Genetic Tests

For those of you new to the genetic testing field, you should first have a solid understanding of correlation versus causation. The distinction between these scientific terms can allow you to get the most out of your genetic tests, and truly understand how your genes affect your health and lifestyle. While the two terms are related, the difference between correlation and causation is similar to the difference between an educated guess and knowing the answer outright. Knowing whether a genetic report is based on correlation or causation makes a big difference in how serious you should take the results (or how good is the test kit). First, let’s get an understanding of what correlation and causation actually are. Correlation A correlation is a relationship between two items. These relationships…

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,…

Autosomal testing vs Mitochondrial testing (mtDNA) vs Y-Chromosome testing

Genealogy, science

When going over your options for a direct-to-consumer DNA test, the options can be overwhelming. Between the different companies available, testing methods used, and services provided, it can be hard to choose a company and plan with any confidence. In terms of testing methods alone, there are several approaches different companies take to analyze your genetics. In general, companies tend to analyze up to 3 different parts of your genetic code. The majority of companies test your Autosomal Chromosomes. These chromosomes represent a majority of your DNA. They account for 22 of the 23 chromosomes. The 23 chromosome is your Sex Chromosome, and contains two forms: X and Y. Females have a pair of X chromosomes, while men have an X and a Y. Because the Y is always passed down…

Criticism about Home Genetic Testing

Genealogy

As much as direct-to-customer home DNA kits have been sparking interest across the globe, there has been rising criticism about them. The criticism is normally not geared at one individual company (while 23andMe are taking most the heat being the biggest and running into trouble with the FDA in the past) but rather about the concept of offering DNA kits to people and supply information which is either not accurate enough or cannot be used clinically. Everyone loved 23andMe and other home genetic test kits as long as they focused on novelty; when marketing started focusing on personal DNA kits as a diagnostic tool, that's when all hell broke loose.
