Israeli rabbis are soon to meet to determine whether the Jews of Mizoram / Bene Menashi are "really jewish" and therefore entitled to excercise claims under the law of return. No word on whether the genetic test for the Cohen gene has been performed, like with the Bene Israel of India or the Lemba of Southern Africa.

p.s. Mizoram is a state at the eastern edge of India, just to the south of Assam, sandwiched between Bangladesh and Burma. These are desis who claim to have been a "lost tribe" but whose claims are fairly recent.
