Is there known biology to link Hars2 with App?
69 SNPs, 1 cSNP:
6 exons in NCBI,
2 exons in Celera
 Not obvious
Hars2 is not a well characterized gene and their is no biology yet to support the hypothesis that Hars2 modulates gene expression, let alone App expression in specific. There are also serious database/assembly discrepancies between Celera and MGSCv3 regarding the genomic organization of this gene. But there appear to be approximately 69 SNPs in Hars2, one of which results in a substitution.
