Hi, I have information about the mutation of mitochondrial DNA J1c5c?
According to Eupedia's mtdna J page, J1c5c is connected with the Basques.

It may be a mistake
Even if you are not from the Basque Country, one thing is for certain. J1c was Mesolithic Balkans whom got absorbed by Neolithic Farmers/Herders. A Neolithic arrival to Spain would give J1c5c might give an Ancient Iberian origin; J1c5 is found all over Europe.
