To do this, 13 differenitally expressed genes incldung P2RY14, INHBA, MAOB, KCNB2, PTHLH, NKIRAS1, TRIB1 and CXCR4 were randomly selected and the transcript abaundances of these genes in samples derived from SE, CE and HE animal groups were measured using qRT-PCR. The gene discussed is KCNB2; the disease is hereditary elliptocytosis.
