SHISA6 and myopia: For SHISA6 and RBFOX1, although no relationships with PONV have been reported, two SNPs in these genes, rs2908972 and rs10500355, respectively, were interestingly shown to be strongly associated with myopia (p = 5.000 × 10−24 for rs2908972; p = 2.000 × 10−63 for rs10500355) [48] according to the Phenotype-Genotype Integrator (PheGenI), which is available in the NCBI database.
