Because this SNP (rs3751248) is located in an open chromatin region, neither of the two scenarios can explain the case whereby the target site has a functional effect on genes other than GNPTAB. In such a case, our findings may be attributed to genetic hitchhiking, where alleles in dyslexia-related genes may increase their frequency together with the linked target site, which could have functions for other genes and traits other than reading ability. Here, GNPTAB is linked to dyslexia.
