For the six genes common between CHH and CHG, the DMR for four genes (ENSOARG00020000663, EPCAM, ADAMTS15, and PLXND1) were in the intergenic region, whereas for the other two genes (MAGI1, TVP23A) the DMR was in the intronic region. The gene discussed is TVP23A; the disease is cartilage-hair hypoplasia.
