The in vitro mammalian cell gene mutation test can be used to detect gene mutations induced by chemical substances. In this test, the used genetic endpoints measure mutation at hypoxanthine-guanine phosphoribosyl transferase (HPRT), and at a transgene of xanthineguanine phosphoribosyl transferase...

This Test Guideline describes an in vivo erythrocyte Pig-a gene mutation assay (hereafter called the Pig-a assay) which uses an endogenous mammalian gene, the phosphatidylinositol glycan class A gene (Pig-a), as a reporter of somatic-cell gene mutation. In vivo gene mutation tests, such as the Pig-a assay, are especially relevant for assessing mutagenicity because physiological factors, such as absorption of the test chemical from the site of exposure, distribution of the test chemical throughout the test system via systemic circulation, and in vivo metabolism and DNA repair processes, all contribute to the mutagenic responses.
