Short tandem repeats (STRs)과 single nucleotide polymorphisms (SNPs)를 이용한 2촌 관계 분석
Using short tandem repeats (STRs) and single nucloetide polymorphisms (SNPs) for full-siblings analysis
STR and SNP have been widely used genetic markers to confirm family relations. STR has been deemed very useful marker to confirm human identif ication and relations due to that everyone has different short tandem repeats (STRs) which is inhe rited indepe ndently. Des pite of weaker power of locus discrimination compared with STR, SNP features lower mutation rate (10·8) and binary polymorphism, which facilitate confirmation of family relations. In addition, applying next generation sequencing is now able to experiment larger number of SNP markers. In this study to determine relations of sibling, 17 STR and 169 SNP markers were used to see whether these markers have confidence to be used in the fi eld. 17 STR markers were detected in the full-sibling analysis and 140 SNP markers were analyzed among 169 SNP markers. When likelihood ratio value is more than 1, all true positive were detected (43 pairs), false negative were not detected and faJse positive pairs were more detected STR (47 pairs) than SNP (S pairs). Therefore FuJJ-sibJing anaJysis was efficient to use with the STR and SNP.

법과학 분야는 사회정의 구현에 있어 크나큰 가치가 있음에도 불구하고 우리나라에서는 이 분야에 대한 인식이 미흡하여 선진 외국에 비해 침체되어 있는 실정이다. 이에 우리나라에서도 법과학 분야와 관련 있는 학계, 연구기관, 수사기관 등 유관 단체들로 구성된 한국 법과학회를 창립하여 이 분야를 활성화 시켜 과학수사를 한층 더 발전시키기 위함을 목적으로 한다.
