Human hepatocyte nuclear factor 4 (hHNF-4) is a member of the nuclear hormone receptor superfamily and an important transcription factor and developmental regulator of liver-specific genes. Distinct hHNF-4 cDNAs corresponding to various HNF-4 isoforms have been recently characterised. Three cDNAs, hHNF-4A, B and C, are considered splice variants of a single hHNF-4 gene. We have mapped hHNF-4 to 20q12-q13.1 between PLCG1 and D20S17 by genetic linkage analysis, taking advantage of an adjacent PstI restriction fragment length polymorphism, (RFLP), and by fluorescence in situ hybridisation. hHFN-4 maps to chromosome 20 in a region syntenic with mouse chromosome 2 where the hnf-4 homologue has been assigned.
