Crypto-Jewish mtdna?
Hi all, I just got my Mtdna results back I have the T2b11 haplogroup with the m.9181A>G mutation. Ive heard this is a crypto-Jewish material haplogroup and was wondering if anyone could back this up! Here are some pictures and some extracts of studies for my claim:
"Sub-haplogroup T2b11 is a rare haplogroup defined by m.9181A>G (in coding region). Within T2b11, three Belmonte lineages shared m.9181A>G, along with a sample from Spain. This motif is absent from global databases (1000 Genomes, GenBank). Hence, the m.9181A>G variant within the T2b11 branch seems to be a regionally specific variant within the T2b11 branch, reflecting a Sephardic signature, preserved locally through endogamy."
"The majority of genetic studies on Jewish populations have been focused on Ashkenazim, and genetic data from the Sephardic original source, the Iberian Peninsula, are particularly scarce. Regarding the mitochondrial genome, the available information is limited to a single Portuguese village, Belmonte, where just two different lineages (a single one corresponding to 93.3%) were found in 30 individuals. Aiming at disclosing the ancestral maternal background of the Portuguese Jewry, we enlarged the sampling to other crypto-Jewish descendants in the Bragança district (NE Portugal). Fifty-seven complete mtDNA genomes were newly sequenced and - in contrast with Belmonte - a high level of diversity was found, with five haplogroups (HV0b, N1, T2b11, T2e and U2e) being putatively identified as Sephardic founding lineages."
"Variant 9181A>G within the T2b11 branch seems to be a regionally specific variant within the T2b11 branch, reflecting a Sephardic signature, preserved locally through endogamy."

"Variant 9181A>G within the T2b11 branch seems to be regionally specific, reflecting a Sephardic signature, given its absence from public databases."
