is a SNP in the vesicular monoamine transporter SLC18A1
gene, encoding a Thr4Pro substitution. In dbSNP orientation, the (G) allele is associated with the Proline.
A study of 62 patients with schizophrenia concluded that the frequency of rs2270641(G;G) homozygotes was significantly higher. The reported odds ratio was 3.74 (CI: 1.7-8.2, p=0.0006) in this population of European descent.[PMID 18451639]
Note: another SNP, rs56575139, marks the same genomic location as rs2270641.
