What does the Glutathione S-Transferase Theta 1 Deletion test measure?

Glutathione S-Transferase Theta 1 Deletion (GSTT1) is a clinical biomarker used in comprehensive-panels assessment. GSTT1 catalyses glutathione conjugation of smaller hydrophobic electrophiles, including certain industrial solvents and halogenated compounds. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Glutathione S-Transferase Theta 1 Deletion?

GSTT1 catalyses glutathione conjugation of smaller hydrophobic electrophiles, including certain industrial solvents and halogenated compounds. Like GSTM1, a homozygous deletion leads to complete absence of enzyme; roughly 10–20 per cent of individuals carry the null genotype, with ethnic variation.

Why is Glutathione S-Transferase Theta 1 Deletion measured?

GSTT1-null has been linked to increased susceptibility to certain chemical exposures and modest cancer risk in gene-environment interaction studies. Combined GSTM1/GSTT1-null status may amplify susceptibility. Clinical application remains exploratory, with genotype informing risk stratification and environmental counselling rather than guiding specific therapies.
