The only connection I have seen between human genetics and the number 666 was that the "total nucleons in the B-component of paired U, G, or C codons = 666" (whatever all that means). It was just one of a bunch of possible numbers - there were a 547, 452, 592, 464, etc., etc., scattered in the nucleon counts also - so this particular "genetic numerical connection" is to me merely a semi-interesting mathematical coincidence. I find it very difficult to believe that any other alleged numerical connection would be any different, especially one with the parameters you mentioned. Intricate calculations make numerical coincidences of this type very likely, if you just crunch enough numbers. As the old statistics saying goes, if you torture the data long enough it will confess to anything you want. Which, when you get down to it, is the problem Irenaeus saw in getting too involved in playing with this number until the time of the prophecy's fulfillment - you can get almost any answer you want.
