So what if Karin is an Uzumaki, because she did say they spread out around the regions.
My thing is on a scale of finding out who is who and who is related to who. Karin being part of his clan really doesn't have too much of an impact on Naruto, She can't tell him what the Cloud village was like, she can't tell him what the other Uzumakis were like.
So he might like that fact he has ACTUAL living family but thats it. I mean she is more useless than Sakura on the battle field foe Naruto. He doesn't need to bite her to heal.
Not bashing cause they way Kishi is writing right now,HELL they might be.
NO actually if you think about it it has a great deal to do with things Karen is a sensor above rival http://manga.animea.net/naruto-chapter-460-page-6.html http://manga.animea.net/naruto-chapter-460-page-14.html http://manga.animea.net/naruto-chapter-460-page-15.html http://manga.animea.net/naruto-chapter-460-page-16.html
She noticed something special in Naruto and can sense things no one else can and healing ability equates to giving /having a long life so she will be able to detect the special chakra of the uzumaki and help Naruto or Madara find other Uzumaki or other specialized clans
