Abstract

Analysis of genetic polymorphisms in short tandem repeats (STRs) is an accepted method for detecting associations between genotype and phenotype but it has not previously been used in the study of the genetics of impulsive violent behavior.
OBJECTIVE:
Compare the prevalence of different polymorphisms in 15 STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA) between men with a history of impulsive violence and male control subjects without a history of impulsive violence.

METHODS:
The distributions of the alleles of the 15 STR loci were compared between 407 cases with impulsive violent behavior and 415 controls using AmpFlSTR(®) Identifiler™ kits.

RESULTS:
COMPARED TO CONTROLS, THE AVERAGE FREQUENCIES OF THE FOLLOWING ALLELES WERE SIGNIFICANTLY LOWER IN INDIVIDUALS WITH A HISTORY OF VIOLENT BEHAVIOR: allele 10 of TH01 (OR=0.29, 95%CI=0.16-0.52, p<0.0001,), allele 8 of TPOX (OR=0.71, 95%CI=0.58-0.86, p=0.0005), allele 9 of TPOX (OR=0.65, 95%CI=0.47-0.89, p=0.0072) and allele 14 of CSF1PO (OR=0.27, 95%CI=0.11-0.68, p=0.0035). One allele was significantly higher in cases than controls: allele 11 of TPOX (OR=1.79, 95%CI=1.45-2.22, p<0.0001).

CONCLUSIONS:
To the best of our knowledge, this is the first behavioral genetic study that clearly demonstrates a close relationship between specific genetic markers and impulsive aggression in non-psychiatric offenders. Further prospective work will be needed to determine whether or not the alleles identified can be considered risk factors for impulsive aggression and, if so, the underlying mechanisms that result in this relationship.

Vernacular Abstract

短串联重复序列基因多态性(short tandem repeats, STRs)分析是用于检测基因型和表型之间关联的公认方法,但它以前没有在冲动暴力行为的遗传学研究中使用。

目的:
在有冲动暴力行为历史的男性和无冲动暴力行为男性对照组之间,比较15个STR基因位点(D8S1179,D21S11,D7S820,CSF1PO,D3S1358,TH01,D13S317,D16S539,D2S1338,D19S433,VWA,TPOX,D18S51,D5S818和FGA)不同多态性的发生率。
方法:
应用AmpFlSTR®Identifiler™试剂盒比较407个有冲动暴力行为的病例和415个对照的15个STR基因位点等位基因的分布。

结果:
有冲动攻击行为历史的人以下等位基因的平均频率显著低于对照组:TH01的等位基因10(OR=0.29,95%CI=0.16-0.52,p<0.0001),TPOX的等位基因8(OR=0.71,95%CI=0.58-0.86,p=0.0005),TPOX的等位基因9(OR=0.65,95%CI=0.47-0.89,p=0.0072),和CSF1PO的等位基因14(OR=0.27,95%CI=0.11-0.68,p=0.0035)。而患者组有一个等位基因频率显著高于对照组:TPOX的等位基因11(OR=1.79,95% CI=1.45-2.22,p<0.0001)。

结论:
据我们所知,本项行为遗传学研究最先清楚表明了特定的遗传标记与非精神病罪犯的冲动暴力行为之间的密切关系。进一步的前瞻性工作将需要确定已辨识出的等位基因是否可以被认为是冲动暴力行为的危险因素以及导致这种关系的基本机制。
