Zim1 (imprinted zinc-finger gene 1) is expressed mainly from the maternal allele in embryos and
neonates. It is biallelically expressed in brain (Kim
J et al, 1999).
Zim1 does not have a human orthologue - see Kim
J et al, 2004 for a discussion of evolution at this locus.
Imprinted maternal expression of Zim1 was confirmed in placenta (Wang X et al, 2011 and Okae H et al, 2012 ).
