Finger and palmar dermatoglyphics of 120 male and 120 female schizophrenics with and without a family history of schizophrenia in first-degree relatives were studied in the northwestern part of India. Patients were selected according to specific diagnostic criteria. Significant dermatoglyphic differences were observed for fingerprint patterns, total finger ridge counts and 'atd' angle between the schizophrenics with and those without a positive family history of schizophrenia, suggesting a strong "genetic loading" (i.e., hereditary factors) in familial cases of schizophrenia. Dermatoglyphic features of isolated schizophrenics also significantly differed from those of controls, thus indicating the involvement of genetic factors in the etiology of schizophrenia.
在印度西北部，对120名男性和120名女性精神分裂症患者的指纹和掌纹皮纹进行了研究，这些患者有无一级亲属精神分裂症家族史。患者根据特定诊断标准选取。在有精神分裂症家族史阳性和无精神分裂症家族史阳性的精神分裂症患者之间，观察到指纹模式、总指嵴数和“atd角”存在显著的皮纹差异，这表明在精神分裂症家族病例中存在强烈的“遗传负荷”（即遗传因素）。散发性精神分裂症患者的皮纹特征也与对照组有显著差异，从而表明遗传因素参与了精神分裂症的病因学。
