NDN (Necdin (mouse) homologue) is paternally expressed in brain (human and mouse) and fibroblasts.
It is expressed in
differentiated neurones (MacDonald HR et al, 1997; Jay P et
al, 1997; Watrin F et al, 1997).
Bisulfite sequencing revealed a bias towards maternal allele-specific DNA hypermethylation of the
promoter CpG island of NDN, independent of tissue-specific transcriptional activity (Lau
C.Y.J et al, 2004).
