“…Since 2009, the research team at University of Texas Health Science Center at Houston (UTHealth), in collaboration with investigators at the University of the West Indies (UWI), have conducted two phases of an age‐ and sex‐matched case‐control study to investigate the role of the GST genes (e.g., GSTP1 ) and their potential interactions with five metals, lead (Pb), mercury (Hg), arsenic (As), cadmium (Cd), and manganese (Mn), in relation to ASD in Jamaica. Details on the recruitment and assessment procedures of this study have been reported previously (Rahbar et al., , , , , , , , ). So far, a significant gene‐environment interaction between GSTP1 and Mn was found when Mn was the only metal that was assessed (Rahbar et al., ).…”
