The web page http://pathology.jhu.edu/pc/GTBRCA2Jews.php?area=Support

has the following:

It turns out that an ancestor of Eastern European Jews, approximately 29 generations or 3000 years ago, developed a defect in the DNA coding for the BRCA2 gene.

The part of the statement of 'approximately 29 generations or 3000 years ago...' is wrong.

Generations are not in excess of 100 years. They are defined in the life sciences as being the time it takes for an individual to first reproduce.

For people, that is about 25 years, so 3000 years is 120 generations, not 29.

In my own family, where I traced from a grandchild to the oldest in the family tree (not through the first born), the average of 15 generations is just over 30 years. So, 29 generations would be just under 900 years, not 3000 years.

The web site does not seem to have a place to contact the web master or anyone else.

If someone can find a contact, I would appreciate knowing the contact information.

Thanks much,

John (I was diagnosed with pancreatic cancer in November and finding this list is very helpful.)
