IN-VIVO MUTATION AT THE HUMAN HPRT LOCUS

The molecular nature of mutations that arise in vivo at the human hypo xanthine-guanine phosphoribosyltransferase (HPRT) locus can be determi ned A wide variety of such mutations can be detected, including large and small deletions, frameshift mutations and single-base substitution s, as well as alterations that cause aberrant mRNA splicing. Here, we review the available information on mutations at this locus.
