Ancestry.com has posted the following information from its DNA testing group:

Ancestry.com DNA has recently updated a Y-chromosome DNA test marker name and its allele value to comply with a recently released industry-wide recommendation by the International Society of Genetic Genealogy (ISOGG).

One of the markers in our Y-chromosome DNA test has changed names from “Y-GATA H4.1″ to “Y-GATA H4“.  The allele value of “Y-GATA H4″ has also changed.  This has been done based on the recommendation of ISOGG and a consensus of genetic genealogists.  This will not affect purchasers’ current haplogroup assignments.

Ancestry.com DNA is committed to providing our customers with the most current and relevant results for family history research.  As other companies adjust their results to match the new standard, results will be more easily compared with the results in their databases and the results entered manually into our database.

For those of you that have purchased a Y DNA test you don’t need to take any action, but you can view your updated results right now.
