Moreover, since this SNP is closer to another gene, HABP2, we should not ignore the possibility that our 10q24–q26 region harbors more than one schizophrenia susceptibility gene, acting independently: TCF7L2 and HABP2. Moreover, a third susceptibility gene for schizophrenia, FGFR2, was found in this genomic area by O'Donovan et al (2009) [25]. Here, TCF7L2 is linked to schizophrenia.
