Expression states 1 and 2 refer to alleles that do not display allele-specific expression (ASE). Expression states 3 and 4 refer to alleles that do display ASE, for example, due to imprinting (ASEi) and X-inactivation (ASExi). Expression state 5 refers to alleles that display differential ASE (ASEΔ), due to currently unknown mechanism(s). |
