Jc. Law et A. Deka, IDENTIFICATION OF A PSTI POLYMORPHISM IN THE P21(CIP1 WAF1) CYCLIN-DEPENDENT KINASE INHIBITOR GENE/, Human genetics, 95(4), 1995, pp. 459-460
A PstI polymorphism in the 3' flanking region of the p21(Cip1/Waf1) cy
clin-dependent kinase inhibitor gene is described. DNA sequencing anal
ysis identified a C-->T base substitution in the 3' flanking region of
the gene. This substitution leads to the destruction of a PstI site a
nd results in a biallelic DNA polymorphism. This restriction fragment
length polymorphism (RFLP) provides the first known genetic marker for
this cell cycle regulatory gene.
