The former four genes were belonged to krupple - type zinc finger family and irxl was belonged to iroquois homeobox family . both of the families are transcription factors . it was shown that the two family proteins are involved in the cardiogenesis process or cardiac disease 前面4个基因属于c2h2 -型锌指蛋白家族， irx1属irx蛋白家族，它们都是转录因子，研究表明这两个家族蛋白都参与心脏的发育或疾病发生过程。
