rs1800972(G;G) homozygotes appeared be at less risk (by a factor of 3.3, p=0.01) for Crohn's disease, based on a study of 190 Caucasians.[PMID 17943629]
[PMID 19390326] Based on a study of ~300 HIV-infected mothers, to whom were born ~100 HIV-infected children and ~200 uninfected, rs1800972 was associated with a modified risk for HIV transmission from mother to child. In children, the rs1800972(G;G) genotype and the rs1800972(G)/rs1799946(G) haplotype had a protective role against HIV-1 infection [odds ratio 0.52, CI: 0.31 - 0.86, p = 0.03 and OR = 0.50, CI: 0.31 - 0.83, p = 0.014, respectively]. In mothers, the rs1800972(G;G) genotype and the rs1800972(G)/rs1799946(G) were associated with low levels of HIV-1 plasma viremia (<1000 copies/mL) and a lower risk of maternal HIV-1 transmission (odds ratio 0.14, CI: 0.03 - 0.67, p = 0.009 and OR = 0.23, CI: 0.08 - 0.66, p = 0.012, respectively).
