Relationship between expression and methylation of obesity
... POMC, PCSK1 and MC4R can lead to obesity, these variants are rare and therefore explain only a fraction of obesity’s observed 40–70% heritability (8,10). It is possible that a portion of this unexplained heritability, an example of the ‘missing heritability problem’ (11), is due to epigenetic change ...
