MEF2 genes belong to the MADS box family of transcription factors and encode proteins that bind as homo- and heterodimers to a consensus CTA(T/A){sub 4}TAG/A sequence present in the regulatory regions of numerous muscle-specific and growth inducible genes. Sequence analysis of human MEF2 cDNA clones suggested that they arose from alternatively spliced transcripts of four different genes, termed MEF2A-D. We have mapped the MEF2 genes to human chromosomal regions by identifying unique sequences in the 5{prime} or 3{prime} untranslated regions of each clone and using these sequences as PCR primers on the DNA of a human-rodent hybrid clone panel informative for different regions of the human genome. The localization of MEF2A to chromosome 15q, MEF2B to 19q, MEF2C to 5q, and MEF2D to 1q verifies the existence of at least four distinct loci for members of this gene family. The same PCR primers were used to identify individual YAC clones for each gene. Such isolated clones are now being used for fluorescence in situ hybridization for high resolution chromosomal regional assignment.
