Don't think so.
Is Chess Genetic ??
Well, partially for sure. Partially, environmental as well. For example, a tree can't play chess as far as we know, and it's because a tree's gnome doesn't include the necessary genes. But environment would be key. If one was raised in a chess environment their genetic potential would be more likely to be reached.
People with autistic tendencies or eidetic memory have a gigantic advantage over regular people, if only they were interested in chess (most are not).
An autistic person could in theory even devote his life to memorizing all the possible openings and variations in random 960 chess and crush any opponents. It wouldn't be an extraordinary feat;
There are some autists who can even recall an exact landscape they havepreviously seen and draw it building by building with minute details.
To answer OP, there is no gene that magically makes you a good chess player. Neither does being a savant or having eidetic/photographic memory, but it would certainly help since your capacity for memorizing things would be exponentially higher than that of a regular person.

The author of a new book says genetics rather than chess lessons have a bigger effect on success. Bryan Caplan an Economics Professor at George Mason University in Virginia studied identical twins and based his findings on twins who shared the same genes but were seperated at birth and brought up by different families.
Conclusion:
"Kids literally inherit educational and financial success from their parents."
Well Magnus Carlsen can play over 20 games at the same time without seeing the bord. I think this is really near to autistic tendencies. Also you have to keep in mind that only a really small part of autistic kids are that genious. Most of them has the potential but never use it.

In the case of say one in ten Autistic persons who show savant syndrome directing their energies towards chess it would be interesting to see if this gene variation would allow chess mastery...........Much of chess is memorising move variations which they would excel in.

Yeah, which they would wtih Excel in. I got to 2200 without memorizing a single page. Must have been all drunk. My genes are of a German Spitz, dominant black with the liver gene (bb), which has turned its solid black coat into brown, and the Greyhound and Weimaraner with the dilution gene (dd) added on top, making them blue. In the dog world it is possible to be genetically black without actually being black!
If it is I must have skipped a generation.............
