Genes affected

GSTP1 (HGNC:4638): (glutathione S-transferase pi 1) Glutathione S-transferases (GSTs) are a family of enzymes that play an important role in detoxification by catalyzing the conjugation of many hydrophobic and electrophilic compounds with reduced glutathione. Based on their biochemical, immunologic, and structural properties, the soluble GSTs are categorized into 4 main classes: alpha, mu, pi, and theta. This GST family member is a polymorphic gene encoding active, functionally different GSTP1 variant proteins that are thought to function in xenobiotic metabolism and play a role in susceptibility to cancer, and other diseases.

Collection Method: clinical testing

The c.520T>A (p.F174I) alteration is located in exon 7 (coding exon 7) of the GSTP1 gene. This alteration results from a T to A substitution at nucleotide position 520, causing the phenylalanine (F) at amino acid position 174 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
