Exploring Family Health History: DNA and Your Health

Exploring our family health history is just another reason to look forward to the future of DNA testing. As science advances and we find out more regarding the specific genetic code responsible for various nefarious outcomes in our health, we learn there is more in play than just our genetics.

I recently read an article in the Wall Street Journal about a family who has been plagued with sudden deaths, ten in recent generations. Without warning, their hearts were stopping and no one knew why. That is until Daniel Wiggins died suddenly at the age of 29 and his family sought out a molecular autopsy. Becoming more accessible to researchers as the cost of running these tests drop, molecular autopsies allow a scientific team to analyze the DNA of the deceased, looking for genetic clues to the cause of death. In this case, the genetic sleuthing was able to turn up the perpetrator: a mutation that alters the electrical signals in the heart, causing it to stop. [Read more about this here.]

While this case was clear-cut and the gene was acting seemingly alone without an accomplice, researchers of this disorder say it only happens in 20% of cases. Which means, this devious genetic criminal has other methods we still haven’t tracked.

But for Daniel’s family, they can pursue genetic testing to determine if this specific culprit is lurking in their own genes. If found, they can take precautionary measures, like having a defibrillator installed.

Doing Our Part

Similarly, a family from Pennsylvania used their family reunion as a format for gathering family history and genetic information in order to arm its members with an action plan against a plague of cancer that is sweeping through their family. [See an article on this family here.]

Several members of the Shaffer-Peterson family have discovered a genetic test can alert them to possible pancreatic or skin cancer. Again, a gene affecting a very small number of melanoma patients was identified as the perpetrator of the Shaffer-Peterson family  and has been given a 67% crime rate. This means that the chance of developing cancer if you have this particular gene is elevated by 67%.

Thankfully, melanoma is a particularly curable kind of cancer when caught early. This family has done their part in informing the family as a whole. And, they now have a sort of insurance plan that may protect the lives of their loved ones.

For both the Shaffer-Petersons and the family of Daniel Wiggins, genetic tests produce actionable results to those testing positive. There is something they can do to positively impact their health once they are aware of the presence or absence of these genes in themselves.

Environment or DNA?

Not all diseases or conditions can be attributed to our DNA. This past fall, after talking with my mother about kids and schedules, she added almost in passing, “Oh, by the way, they found another spot on my back, I am going to have it removed next week.” This is the third melanoma spot she has had removed in the past 5 years.

While my mom’s melanoma is less likely to be the result of a genetic abnormality and more likely linked to spending hours lifeguarding at the local pool, the fact she had melanoma was the sole reason I went to the dermatologist. My spot wasn’t cancer. I was just getting older. But, I am glad I went and I feel like knowing my health history has made me more aware of the measures I can take to improve it.

For most people, molecular autopsies and DNA health tests are not easily available. Not yet. For those that are, there are hundreds of questions surrounding the kinds of genetic tests and the implications for both health and legal issues.

One thing is certain. In these cases, the common thread is family history. We need to know not only the dates and places of our ancestors lives and deaths, but also the stories behind them. Whenever possible, we need to track our health history, so we can identify any trends that our DNA might be trying to tell us.

If you want to start tracking your own health history there are plenty of free and subscription online tools to get you started. In particular, TapGenes was the winner of the 2016 Innovator Showdown at RootsTech. This online and app tool is designed specifically for your family health management.

You can also create your own alternate family tree. In this unique way, you can visually look at age-at-death, diseases, or other factors pertaining to your health. Read our article titled, “How and Why to Create an Alternate Family Tree.”

Just after RootsTech 2018, Your DNA Guide Diahan Southard reports on the latest DNA news you’ll want to know.

NEWS: DNA NEWS ROUNDUP 

First up was MyHeritage, showing their support for the 7 million adopted individuals in the United States with their new DNA Quest campaign. MyHeritage will provide 15,000 DNA test kits to eligible participants free of charge, in order to help these adoptees use DNA to reunite them with their biological families. With this initiative they “hope to make this project a shining light for corporate philanthropy and an example to be followed by other commercial companies in their own lines of expertise to make the world a better place.” MyHeritage has assembled an advisory board of genetic genealogists and genetic counselors to help drive this project and ensure it meets the needs of the community. If you or someone you know is interested in participating, you can head on over to the DNA Quest website (www.dnaquest.com) to fill out an application. But you better hurry, the application deadline is April 30, 2018.

Next, addressing the biggest problem in genetic genealogy, namely the looming What Next? question facing millions of newly swabbed participants, MyHeritage announced the Big Tree ? a giant network of genetic and genealogy results that will automate much of the match comparison and tree searching to replace your head-scratching with light-bulb moments. They have already made significant headway on this project, as reported in the journal Science, which MyHeritage’s own chief scientific officer Yaniv Erlich collaborated on. The journal reports that the team of scientists successfully extracted public family trees from Geni.com (a MyHeritage daughter company), and then used a computer program to clean up and link the trees together. It sounds like MyHeritage will be adding genetic data to this kind of tree data in their Big Tree project.

MyHeritage isn’t the only company out to improve the DNA matching experience. UK based LivingDNA announced that they plan to add DNA matching to their popular origins test by third quarter 2018. When they launched in October of 2016, LivingDNA was not offering cousin matching, but opted instead to focus all of their resources on providing very detailed origins reports, including breaking down the UK in to 46 categories. In the months since their launch, they have been working on a genetic matching system, called Family Networks, that will appeal to a wide range of users and will “reduce the risk of human error and take away the tedious task of figuring out how each person on a user’s list are related to one another.” They are promising an experience that provides “a level of relationship prediction and specificity beyond anything currently on the market.”

So it sounds like if you are currently struggling with turning your DNA matches into genealogical discoveries, our testing companies want you to know you are not alone, and they are working hard to provide solutions to these problems. Time will only tell if they can succeed.

Diahan also provides answers to questions asked about this blog post announcing updates to MyHeritage DNA matching technology and its new chromosome browser.

INTERVIEW: SAM GILL, FILM HISTORIAN AND ARCHIVIST

Shown here: Sam Gill and Lisa Cooke at the Niles Essanay Silent Film Museum on the day of this interview. Throughout their conversation, you hear the sounds of excited theater patrons filling the auditorium before a screening.

Sam Gill’s interest in silent film dates to 1966, when as a college student he traveled to Hollywood to interview his aging heroes from the silent screen comedy era. For more than 20 years, he was Archivist of the Academy of Motion Picture Arts and Science’s Margaret Herrick Library, where he established the Academy’s Special Collections and helped it grow to its current status as the preeminent repository for the study of American cinema. He is currently a Board Member of the Niles Essanay Silent Film Museum. Over the years, he has consulted on or otherwise contributed his expertise to numerous film festivals, museum film programs and film history books.

Sam recently sent us these delightful photos (below) of himself over the years:
