    informations about L2a1c6

    Hello everyone

    i have received my WGS results and my mtdna is L2a1c6



    the samples without flag are from france , portugal , spain

    can we say that L2a1c6 is a mediterranean clade of L2? cause i didn't found enough informations about it

    thank you

    Hi Imesmouden.

    My dad is a match with you at Yfull - he's the tester from Malta in the image you posted.

    Most (but not all) of his mtDNA matches at FamilyTreeDNA are Maltese as well. There are two studies that might be worth checking out, though both only looked at HVR1 and HV2 regions and focused on genetics of Maltese population. A 2016 study by Josef Caruana, found that almost 13% (17/136) of Maltese testers belonged to the L2a1c6 haplogroup. There's, also a 2018 conference paper which suggests a similarly high proportion of L2a1c6 among Maltese testers:

    The Maltese Archipelago has an area of 316km 2 and over 475,000 residents. The islands have a rich demographic history. Although historical records trace population origins to the Temple people, contemporary Maltese are descendants from those who re-populated the islands at the turn of the first millennium AD. Maltese mitochondrial DNA (mtDNA) data is not publicly available. A new high-quality mtDNA control region (CR) dataset was set up to evaluate Maltese maternal lineages. A total of 798 samples were collected randomly with associated ancestry data from Malta and Gozo. This population collection is archived in the Malta BioBank (BBMRI.mt). The EMPOP protocol was used to amplify and sequence a subset of 300 samples with a minimum of four EMPOP sequencing primers according to forensic quality guidelines.

    So far, 284 full CR sequences were typed of which 190 were unique (67%). mtDNA haplotypes were checked on EMPOP and Phylotree and haplogroup frequencies were calculated. The majority of the observed Maltese mtDNAs (77%) could be attributed to Westeurasian haplogroups: H (35%), T (18%), K (12%), J (5%), U (5%), X (1%), W (1%). African mtDNA lineages were also present: L1 (0.4%), L2 (10%), L3 (1%), M1 (0.4%). Other lineages were observed at frequencies of 0.7%-6%. The frequency of haplogroup H in Malta was similar to that in Sicily and Southern Italy (35%). Sub-Saharan L2 and L3 lineages were present at higher frequencies than in Sicily and Southern Italy. The observed sub-clade L2a1c6 was previously reported in Spain (Galicia) and Portugal and is estimated to be 1,700 years old. The presence of L lineages in Malta represents the sub-Saharan gene flow into Europe. This population genetics research provides a first insight into the matrilineal origins of the Maltese.
    Personally, I'm curious whether there's any link between the original bearers of this haplogroup, Arab settlement in Malta, and the evolution of Maltese from its Arabic base.

    Thank you so much for these informations

    i wonder how this clade arrived to south europe and when

    for the arab settlement i don't think so , in my opinion the clade is present there for an older time

    and btw my most distant maternal ancestors is a berber and not arab.

    The Arab-speakers who introduced Arabic to Sicily were mainly Arabized Berbers (or Arabized in situ). That's reflected in the position of Maltese and Siculo-Arabic close (or part of/offshoot of) Western/Maghrebi Arabic.

    Could also be an earlier introduction of course.

    How did you find that sample JQ is from Spain?
