RESUMO

Objective To explore the distributional differences of the gene frequencies of 22 short tandem repeats loci on Y Chromosome(Y?STRs) between offenders with Initiative?aggressive behavior and impulsive?aggressive behavior,and to probe into the genetic factors of initiative?aggressive behavior and im?pulsive?aggressive behavior. Methods Biological samples of 271 offenders with initiative?aggressive behav?ior and 271 offenders with impulsive?aggressive behavior were collected and PCR compound amplification was carried out with the aid of PowerPlex Y23 System. Then the PCR products were subjected to electrophoresis and gene detection with AB3500xL gene analysis system so as to calculate and compare the alleles and haplo?types of 22 Y?STRs gene frequency in the two groups. Results The distribution of allele frequency were sig?nificantly difference in locus DYS437(P=0.022) between two groups,not in the other 21 Y?STRs loci( all P>0.05) . Univarite analysis showed significant differences at allelle 14 in locus DYS437 between both groups ( initiative?aggressive behavior group:69. 37%;impulsive?aggressive behavior group:58. 67%; P=0. 009 ) . Conclusion Loci DYS437 may be associated with aggressive behavior. In the group of aggressive behavior, allelle 14 on locus DYS437 may be the susceptible factor of initiative?aggressive behavior and the resistant factor of impulsive?aggressive.

RESUMO

Objective To investigate the relationship of the initiative-aggressive behavior and D2S1338,D19S433 loci.Methods PCR and electrophoresis method were used to conduct genotype analysis on D2S1338 and D19S433 in the peripheral blood of 187 male initiative-aggressive violent offenders and 459 healthy men living in Jiangsu area.Results D2S1338 and D19S433 loci in initiative-aggressive behavior group and healthy group were found to coincide with Hardy-Weinberg equilibrium (P > 0.05).There were significant difference in locus D19S433 (P < 0.05)between initiative-aggressive behavior group and healthy group,but not on locus D2S1338 (P>0.05).Univariate analysis showed significant differences at allele 14.2 and genotype 14-14 on locus D19S433 between the two groups (P =0.0011,P =0.0008) with the OR values being 0.50 (95 % CI:0.33-0.76) and 3.49(95% CI:1.62-7.52),respectively.Conclusion Locus D19S433 may be related to with initiative-aggressive behavior with allele 14.2 being the resistant factor and genotype 14-14 being the susceptible factor.
