Genetic Variations of Glutathione S-Transferase Influence on Blood Cadmium Concentration

Table 2

Geometric means of blood cadmium concentrations in a nonoccupational exposed population categorized by different genotype.

Gene	Genotype	Frequency		Blood cadmium (μg/L)
		n	%	GM ± SE
GSTT1	Null	121	32.7	0.49±0.03
	Present	249	67.3	0.44±0.02
GSTM1	Null	213	57.6	0.47±0.02
	Present	157	42.4	0.44±0.02
GSTP1-105	Ile/Ile	212	57.3	0.45±0.02
rs1695	Ile/Val	139	37.6	0.45±0.03
	Val/Val	19	5.1	0.71±0.08^a,b

^a,b Significantly different GSTP1 from Ile/Ile and Ile/Val genotypes, respectively, 𝑃<0.05.
