Is it possible that its more of a line breeding trait than a dominant or recessive? If its popping up randomly and does "accidentally" mix well with other morphs instead of a consistent Dom/co-dom proven gene. I bought a breeder female recently from Family Reptiles at repticon kissimmee a couple days ago for 50$ and just took it as a cool looking normal at the very least but can see subtle differences in patterning and coloration that make me believe that there's a possibility its not just a pretty normal. With that said I can't find any information on the Harlequin gene anywhere but here.
