Abstract excerpt

The GT6 glycosyltransferases gene family, that includes the ABO blood group, shows a complex evolution pattern, with multiple events of gain and loss in different mammal species. In humans the ABO gene is considered the sole functional member although the O allele is null and is fixed in certain populations. Here, we analyze the human GT6 pseudogene sequences (Forssman, IGB3, GGTA1, GT6m5, GT6m6, and GT6m7) from...
