Why you might want to test for DNA health results at MyHeritage

Sep9

The live streaming from the MyHeritage conference in Amsterdam this past weekend was both informative and enjoyable. I was even able to watch without getting up in the middle of the night as they stayed available afterwards. Many of the talks included information that was not new to me, although I was pleased to finally be able to watch Leah Larkin’s WATO presentation.

Yaniv Erlich

The talk that impressed me the most was the one by Yaniv Erlich in the middle of day 2 about the DNA health results that MyHeritage is now providing (on a reduced price sale just through Tuesday, Sept 10). With the acquisition of Promethease and SNPedia they have greatly expanded their access to medical genetic knowledge. SNPedia is always my go to resource for looking up specific genes, for example click here to see what it says about the BRCA genes. While Promethease is where you can upload your raw DNA from wherever you tested to get health results (sadly written in formal medical talk) based on current but not always solid research (see comments below) and is linked to SNPedia.

One of the important take aways for me was that if MyHeritage finds a bad mutation in your test, they will use a different method, Sanger sequencing, to confirm the result! This almost completely eliminates false positives. Still if you are diagnosed with a really bad variation, my opinion is that you should double check even further by getting a doctor ordered test like the one from Color Genomics.

Yaniv also emphasized that they have worked hard to present the results in an understandable format. There are some examples of this on their blog (click here).

Too many figs this year!

Sep4

It’s a wonderful problem. I have way too many figs this year. I eat two or three every morning while I pick about twenty or thirty more. Below is a picture of two days worth of picking, Time to dehydrate them.

My tree is about 60 feet tall and the wild parrots eat the figs on the top half. Sometimes the parrots are lower down where I can take a video …

I dehydrate the figs and then freeze them but there is very little room left in my freezer and I have not talked my husband into buying a separate one for the garage. So I posted on my neighborhood facebook page that I would trade for lemons (my tree is on hiatus til October) or cucumbers or squash.

Help Collect DNA Statistics

Aug24

Many families have grandparents or great grandparents who are first or second cousins. Within family marriages did not used to be as unusual as they are today. However for those of us who work with DNA, the extra relatedness adds confusion to interpreting the comparisons of their descendants. Plus there are people whose parents are related. It would be nice to have some charts showing the expected DNA amounts in these more unusual relationships.

Some of you are familiar with the statistics Blaine Bettinger has collected for more ordinary relationships. (Click here to contribute your numbers there) The calculator at DNApainter, which we all use to check the possibilites for an unknown DNA relationship, is based on his research and the statistical work of Andrew Millard and Leah Larkin.

Now Blaine is collecting the data for these more unusual relationships. So any of you who have DNA results from known double cousins or other family members whose descriptions fit, please click that image below to go to the form where you can add your numbers to his new project.

Creating a GEDCOM from a text file

Aug17

The purpose of this post is to announce new features for my Ahnentafel list to GEDCOM Conversion Tool. The link for this new version is: https://kittymunson.com/dna/Ahnen2GEDv2.php
Once I am confident that it works as it should, the previous version will be replaced with this one.

So why would you want to use this tool?

One way to look for any ancestors you might share with a DNA match is to take a GEDCOM of their pedigree and add it to a copy of your genealogy database to see if there are any duplicate profiles. Other ways are to use DNA2Tree or GWorks (click either for those posts). Often I just visually scan a compact list of my match’s ancestors using the new feature at 23andme, WIKItree’s compact tree, or an Ahnentafel list. Unless, of course, Ancestry‘s ThruLines or MyHeritage’s Theory of Family Relativity have found the common ancestors for me already.

This is the Ancestry tree for the grandmother of my new South African cousins with Pedigree Thief

Did you know that you can get an Ahnentafel list of a person’s ancestors from almost any online family tree displayed in pedigree format via a Chrome add-on called, appropriately, Pedigree Thief?

Better yet, did you know that you can make a GEDCOM from an Ahnentafel list via my tool, Ahen2GEDcom. Click here for my old post about that.

Although my program was originally written to turn the output from DNArboretum and Pedigree Thief into a GEDCOM, some people have found more uses for it.

For example, you might have a document that your Uncle Fred made and you would prefer to use ‘replace all’ in a word processor to cutting and pasting each bit of information into a genealogy program or website. Or you might be collecting information from relatives via spreadsheets or google forms (which can make spreadsheets). Any plain text file can be used as input to my tool, including a CSV file, as long as it is formatted the way the program expects it.

Debbie Parker Wayne is using an online form to collect information for a project of hers, so she asked me if I could enhance my tool to add marriages and sources. I said, “Sure but it is not trivial and I charge more for programming than DNA work.” She said that her book was doing well and she could pay for this. So we did it.

A computer program like this needs the format to be exact in order for it to work. So here are the details.
