I have discussed about some of the maternal lineages of Malayalis before. At that time I didn't have any idea about my subclade. Recently, I came across a Jewish matrilineage data from yet to be published Doron M Behar's new study. I found my near match in one of the samples. That probably is a Malayali Jew lineage.
I have tested for HVRI and HVRII sequences and I have exact match in the following sequence.
EF556193 Haplogroup M
A73G T152C A263G 309.1C 315.1C G316A T489C A750G A1438G A4769G
T5201C C7028T A8701G T8843C A8860G A9180G T9540C G9947A A10398G C10400T
G10685A T10873C G11719A G12007A C12705T A13105G C14766T T14783C G15043A A15196G G15301A A15326G G15355A T15862C T15968C C16223T T16263C T16519C C16527T
My HVR sequence:
HVR1 : 16223T,16263C,16519C,16527T
HVR2 : 73G,152C,263G,309.1C,315.1C,316A,489C
I most likely belong to mtDNA haplogroup M4* as the complete sequence has mutation at location 12007.
M Derived: (HVR1 sequence)
M50* : 223, 263, 519 (*)
Behar et al. paper is out. I belong to mtDNA M50* subclade of macro haplogroup M4'30.
Ibra has pointed out that the designation M50 has already been used in the study "Austro-Asiatic Tribes of Northeast India Provide Hitherto Missing Genetic Link between South and Southeast Asia", by Reddy et al. (2007). I appears Behar et al. are oblivious of this paper as they declare the designation is a new one. We can expect M50 getting a new name.
