Abstract: 胆囊收缩素(cholecystokinin,CCK)是一种具有广泛生物学活性的脑肠肽,既是胃肠道主要调节激素之一,还广泛存在于中枢及外周神经系统中以神经递质或神经调质的形式发挥重要的生理作用.近年来国内外研究发现,CCK基因上存在多个单核苷酸多态性(single nucleotide polymorphisms,SNP)位点,其中-45C/T,-196G/A变异与多种精神状态如精神分裂症、抑郁症、自杀行为、帕金森病等存在一定的相关性.这些SNP多态性可应用于法医物证学的亲子鉴定和个人识别,并且可能成为某些特殊案例如涉及精神病鉴定、法医病理学的疾病鉴定、异常行为(自杀倾向等)鉴定的辅助指标之一.
