To map in detail the human gene for brain derived neurotrophic factor (BDNF) we have used a PCR-based assay to amplify the gene from somatic cell hybrids containing human chromosome 11 with deletion or translocation breakpoints in the WAGR region. The BDNF gene maps between the FSHB and HVBS1 loci, an interval of approximately 4 Mb at the boundary of 11p13 and 11p14.
