Likewise, DNA methylation at the regulatory regions should become homogeneous and resemble either the maternal or the paternal pattern.
92 The Frat3 gene, for which there is no human homologue, has joined the mouse PWS/AS region, acquiring the paternal pattern of methylation and expression.
The genomic imprinting in SSE has a paternal pattern that is different to that of SE and NS, which generally show an erased pattern of imprinting.
Also, paternal patterns of nutrition during the prepubertal growth period in children in Överkalix, in Sweden, during the nineteenth century are associated with differential risk of early cardiovascular death in their grandchildren [ 180, 181].
A clue to the actual mechanism is provided by the observation that the DNA methylation patterns at the three regulatory regions in urothelial carcinoma cells are indeed homogeneous, but are different from both the maternal and paternal patterns in normal bladder and renal tissues.
The analysis of paternal patterns of migration would be useful to shed light on the substructure and the random mating areas among patrilocal populations, while autosomal and X-chromosomal data could be productively investigated to explore whether sex-biased movements are detectable in the distribution of genome variation.

[ 6] In those pregnancies the paternal antigen pattern is typed, because only if the father is antigen-positive, the fetus is at risk of HDFN.
We investigated whether the loss of maternal allele KvDMR1 methylation (a paternal epigenotype pattern) in BWS IC2 epimutation cases was associated with the grandparental origin of the allele (hypothesising that the LOM might result from a failure to reset the imprinting on the grandpaternal chromosome).
This is somewhat surprising as one might have expected a parental expression pattern (either paternal or maternal expression) since these patterns are commonly assumed to be more prevalent.
