Localization of the human multiple drug resistance gene, MDR1, to 7q21.1

Hum Genet. 1987 Oct;77(2):142-4. doi: 10.1007/BF00272381.


Multiple drug resistance has been shown to be associated with amplification/increased expression of a gene designated MDR. The localization of one member of the MDR gene family, MDR1, to the long arm of chromosome 7 by in situ hybridization is reported.
