[[rs4320932]] is a SNP in the [[IF2]] insulin-like growth factor 2 gene.

A study totaling ~5,000 non-Hispanic white patients with [[ovarian cancer]] found a 13% decreased risk of ovarian cancer per copy of the [[rs4320932]](G) allele carried (CI: 0.81-0.93, P-trend=7.4 × 10e-5).{{PMID|21422097|OA=1
}}

Associated with [[schizophrenia]] in a study of Croatians. Due to the limited number (~100 patients) and diversity of the studied population, more study is needed to confirm any link. The G allele was associated with an increased risk of schizophrenia with P < 0.001.{{PMID|19673036|OA=1
}}

Small size study {{PMID|23677070}} with 212 cases linked the G allele earlier found protective against [[ovarian cancer]] increasing relapse by 3.05 (95% confidence interval CI: 1.47–6.37, P-trend 2*10e-4) and mortality 3.28 (95% CI: 1.64–6.57, P-trend 6*10e-5).
