Haplarithmisis
Haplarithmisis (Greek for haplotype numbering) is a conceptual process in Genetics that enables simultaneous haplotyping and copy-number profiling of DNA samples derived from cells. Haplarithmisis also reveals parental, segregation, and mechanistic origins of genomic anomalies.[1][2] The resulting profiles of haplarithmisis are called parental haplarithms (i.e. paternal haplarithm and maternal haplarithm).
Clinical Applications[edit]
Haplarithmisis enabled a new form of preimplantation genetic diagnosis, by which segmental and full chromosome anomalies could not only be detected but also traced back to meiosis or mitosis.[3][4]
Research Applications[edit]
In its first application in basic genome research, haplarithmisis led to discovery of parental genome segregation, a phenomenon that causes the segregation of entire parental genomes in distinct blastomere lineages causing cleavage-stage chimerism and mixoploidy. [5][6]
