人面部形态刻画的法医遗传学研究进展

Research Progress on Forensic Genetics of Facial Morphological Depiction

法医DNA表型(forensic DNA phenotyping,FDP)分析利用现场遗留生物样本DNA预测个体表型特征,如族群地域来源、身高、体质量、肤色、毛发颜色与形态、虹膜颜色、男性秃发、面部形态和年龄等,为案件的侦查提供线索,其中面部形态特征较为复杂。本文从面部形态的测量采集、面部形态相关基因的研究、面部形态刻画的模型建立及法医学应用和伦理问题等方面进行全面分析,对其最新研究进展进行综述。

Forensic DNA phenotyping(FDP) analysis uses DNA from biological samples left in crime scenes to predict individual phenotypic traits, such as geographical origin of ethnic group, height,weight, skin color, hair color and shape, iris color, male baldness, facial morphology, age, etc., thereby providing clues for case investigations. Among these traits, features of facial morphology are relatively more complicated. This paper makes an overall analysis of the measurement and collection of facial morphology, research on facial morphology related genes, forensic application and establishment of facial morphology depiction model, ethical issues, etc., then summarizes the latest research progress on features of facial morphology.
