Analysis of Genetic Variations And Specific Locus of Banjar Hulu Tribe Through Short Tandem Repeat (STR) Locus Combine Dna Index System (Codis) in Nuclear DNA

Abstract

Based on the 2010 Indonesian Population Census, there are 1,300 ethnic categories with various sub-tribal
details. Ethnic diversity is important in terms of identification, such as natural disasters, accidents, crime,
and the discovery of unidentified corpses that may come from various tribes. Forensic Medicine views
genetic diversity and variation as one of the challenges in identification. Genetic variation and kinship in
Banjar Hulu tribe have never been done.The aim of the study are identify and analyze the genetic variation
of Banjar Hulu tribe through nucleus DNA examination of short tandem repeat (STR) Loci combined DNA
index system (CODIS). This study is a descriptive observational study that aims to explain the genetic
variation of Banjar Hulu tribe. The design of this study is cross-sectional. This study was conducted in two
stages, the first stages is to obtain information on family tree from the study subjects conducted by interview.
Then the second stage is to draw blood from the study subjects’ criteria. Blood is drawn from peripheral
vein. Then, there will be DNA examination and analysis of genetic variation. Result of the study show THO1
allele 9.3 locus, D3S1358 allele 12 locus, and D16S539 allele 12 locus, D8S1179 allele 12 locus are typical
marker for Banjar Hulu tribe. Banjar Hulu tribe have specific loci and alleles.
