DLGAP2 (discs, large (Drosophila) homolog-associated protein 2; a membrane associated guanylate
kinase) was paternally expressed in 8 fetal testes, in which all 4 isoforms were imprinted. However,
and 26 showed "some evidence of imprinting relaxation" in 1 of 6, and 2 of 8 samples respectively
PP et al, 2007). DLGAP2 was not imprinted in fetal whole brain.
Morcos L et al, (2011) found no evidence of
allelic expression bias in lymphoblast and fibroblast cell lines.
