As supporting evidence show, genes that might be related with these two cellular processes also seem to be involved in those disorders, such as MECP2 in Rett syndrome (Li et al. 2014), ODC1 for schizophrenia and other neuropsychiatric disorders (Prokop et al. 2021) and UBE3A in Angelman’s syndrome (Mishra et al. 2009). The gene discussed is UBE3A; the disease is Angelman syndrome.
