This region contains a CpG island that was differentially methylated between a hydatidiform mole
(paternal origin) and a complete ovarian teratoma (maternal origin) (Strichman-Almashanu LZ et al 2002).
In contrast, Weeks
RJ & Morison IM, 2006 found marked variation in methylation within this putative DMR, but no
evidence for a parent-of-origin effect.
