Hmmm, but the same mutation was found in roma gypsies. haplogroups are not the only indicator.

RomaIndian,
It is wrong to look at genetic mutation for a disease as proof of genetic affinity, as much as it is incorrect to look at haplogroup alone. I see any attempt to trace a groups ancestry as some sort of jigsaw puzzle. Haplogroup, mutation for disease etc would be the individual pieces, one among many. The other pieces would be:
- Similarities in cultural practices
- Languages spoken
- Phenotype ( appearances )
- Religion
- Professions practiced , skills possessed
- Sub clusters within a given haplogroup ( this is a very important piece )
- Historical, literary references and sources
- Any folklore both in source and the new groups
- Archaelogical evidence, if any
Of course needless to say, in most cases, no one can ever hope to complete the entire puzzle, but fitting in the majority ( if not all ) of the pieces is good enough to draw inferences that can withstand scientific scrutiny.
