The KDR gene maps to human chromosome 4q31.2----q32, a locus which is distinct from locations for other type III growth factor receptor tyrosine kinases.

KDR (kinase insert domain receptor), a new type III receptor tyrosine kinase gene, maps to human chromosome 4q31.2----q32 by fluorescence in situ hybridization. This differs from the chromosomal locations of other members of this gene family.
