Would a genetic medical condition affect DNA search?

[flahagan]

My brother had the Y-DNA done to 111 markers last year under a surname project and had no matches, other than a distant one of a different surname.

My brother has a congenital medical condition with no known cause, could be a mutation (?)

Would this affect the results?...

Several months ago, I wrote to the administrator of my surname project, hoping to join and get a DNA test through this group. I've never heard back.
Should we just proceed anyway, or do you need "permission" to join one of these groups?
It is my brother who will be getting the...

Hmmm, "here" as in on this forum's website, or "here" as in your signature?...

So should we go the surname route for DNA testing via Family Tree, or go with Ancestry.com or 23andme?
I'm sure my brother will go for the 67-marker test to shoot for the best results, but he won't want to pay over and over.

Gaye, I can only say I have LOADS of possibles in my "shoebox" on Ancestry, because like you, I don't want to lose track of them. It's quite a hunt, isn't it?

It did help me find my Murphy ancestors and put me in touch with 2nd and third cousins I didn't know existed, but it only happened...

Oh, and the photos on Tom's tree are mine - so at least I know THEY'RE accurate.

Yes, Tom Casey is my first cousin whom I know well! Unfortunately, he has no idea who Peter's parents are either, he just found a couple who had a son named Peter, who would have married YEARS after our Peter was born, in Rhode Island instead of Ky. or Ohio, "chose" them to be "ours,"...

Thanks for the suggestions. I have written to the administrators of the Casey surname project and will await their recommendations.
As to the Civil War, I have found a Peter Casey in the enlistment records in Louisville during that time, the year the "draft" was instituted, but I can't...

We've hit the genealogy "brick wall" with my father's paternal line and my brother wants to try the DNA route.
We know the name of our g-grandfather (dad's paternal grandfather), Peter Casey, know that he came to the USA from Ireland in the mid-1850's, naturalized in Cincinnati in 1858,...
