Igf2 (a fetal growth factor) is paternally expressed in humans and rodents. Expression is not
imprinted in the choroid plexus, leptomeninges, and some of the brain (DeChiara
TM et al, 1991; Hu
JF et al, 1997), although imprinting was detected in cerebellar granule cells (Hetts
SW et al, 1997). See also Igf2AS, paternally expressed Igf2 antisense transcripts (Moore
T et al, 1997).
