Using data from 266 age- and sex-matched pairs of Jamaican children with autism spectrum disorder (ASD) and typically developing (TD) controls (2-8 years), we investigated whether glutathione S-transferase theta 1 (GSTT1) modifies the association between blood manganese concentrations (BMC) and ASD. After adjusting conditional logistic regression models for socioeconomic status and the interaction between GSTT1 and GSTP1 (glutathione S-transferase pi 1), using a recessive genetic model for GSTT1 and either a co-dominant or dominant model for GSTP1, the interaction between GSTT1 and BMC was significant (P = 0.02, P = 0.01, respectively). Compared to controls, ASD cases with GSTT1-DD genotype had 4.33 and 4.34 times higher odds of BMC > 12 vs. ≤ 8.3 μg/L, respectively. Replication in other populations is warranted.
利用来自 266 对年龄和性别匹配的牙买加自闭症谱系障碍 (ASD) 儿童和典型发育 (TD) 对照 (2-8 岁) 的数据，我们研究了谷胱甘肽 S-转移酶 theta 1 (GSTT1) 是否改变了血锰浓度 (BMC) 与 ASD 之间的关联。在用 GSTT1 和 GSTP1 (谷胱甘肽 S-转移酶 pi 1) 之间的隐性遗传模型对社会经济地位和 GSTT1 和 GSTP1 之间的相互作用进行调整后，使用 GSTT1 的共显性或显性模型，GSTT1 和 BMC 之间的相互作用具有统计学意义 (P=0.02，P=0.01)。与对照组相比，GSTT1-DD 基因型的 ASD 病例的 BMC>12 vs. ≤8.3μg/L 的比值比分别为 4.33 和 4.34 倍。有必要在其他人群中进行复制。
