Apart from genetic triggers of such syndromes, Additionally, there are situations wherever the Snrpn/Ube3A cluster is intact but its genes are epigenetically misregulated. This is certainly As an example the situation if both equally homologs of chromosome 15 originate in the same father or mother, a ailment called uniparental disomy (UPD).
