Other than genetic will cause of those syndromes, Additionally, there are cases the place the Snrpn/Ube3A cluster is intact but its genes are epigenetically misregulated. This is often for instance the situation if both homologs of chromosome 15 originate within the very same mother or father, a situation called uniparental disomy (UPD). Maternal UPD is responsible for PWS, whereas AS is caused by paternal UPD. The origin of UPDs lies in non-disjunction all through feminine meiosis that, after fertilization, causes zygotes that either have only one paternal (monosomy) or two maternal and a person paternal (trisomy) chromosome 15 in the case of PWS and AS.
Numerous hypotheses are actually proposed to elucidate the evolution of genomic imprinting. Between these, David Haig’s parental conflict concept definitely attracted probably the most interest from biologists focusing on imprinting. Haig tried to uncover an explanation why imprinting advanced in such distinctive organisms as mammals and seed crops (Haig and Westoby 1989). He understood that each share a “placental behavior”, i.e., the development of seeds and fetuses depends exclusively on methods furnished by the mother. Certainly, both equally the mammalian placenta plus the endosperm of seed crops are main tissues with imprinted gene expression and Perform a central part in delivering nutrients to the next technology. In contrast, the father contributes tiny to assistance the producing offspring. In polygamous species, this brings about a parental conflict between the paternal and maternal genomes in the progeny because of different kinship associations.

This is particularly correct for imprinted genes in the embryo, exactly where none of twelve tested genes seems to be controlled by DNA methylation and only three ended up influenced by mutants influencing PRC2 (Raissig et al. 2013).
