Genes affected

GSTZ1 (HGNC:4643): (glutathione S-transferase zeta 1) This gene is a member of the glutathione S-transferase (GSTs) super-family which encodes multifunctional enzymes important in the detoxification of electrophilic molecules, including carcinogens, mutagens, and several therapeutic drugs, by conjugation with glutathione. This enzyme catalyzes the conversion of maleylacetoacetate to fumarylacetoacatate, which is one of the steps in the phenylalanine/tyrosine degradation pathway. Deficiency of a similar gene in mouse causes oxidative stress. Several transcript variants of this gene encode multiple protein isoforms. [provided by RefSeq, Jul 2015]

Ambry Genetics

Dec 06, 2021

The c.299G>A (p.R100H) alteration is located in exon 5 (coding exon 5) of the GSTZ1 gene. This alteration results from a G to A substitution at nucleotide position 299, causing the arginine (R) at amino acid position 100 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
