Finger and a-b palmar ridge-count dermatoglyphic features were studied in schizophrenics with and without a positive family history of schizophrenia. Associations are reported for low quantitative dermatoglyphic values in schizophrenia. The differences found between the two subgroups of patients support the genetic heterogeneity of schizophrenia and stress the existence of congenital factors when there is no family history, that is, a genetic background.
对有和没有精神分裂症家族史阳性的精神分裂症患者的手指及a-b手掌嵴纹计数皮纹特征进行了研究。报告了精神分裂症中低定量皮纹值的相关性。在两组患者亚组之间发现的差异支持了精神分裂症的遗传异质性，并强调在没有家族史时即存在遗传背景的情况下先天性因素的存在。
