[Research on the application feasibility of HLA-DRB1 genotyping for forensic identification by oligonucleotide chip].
OBJECTIVE
Research on the application feasibility of HLA-DRB1 genotyping for forensic identification by oligonucleotide chip.


METHODS
Population studies on HLA-DRB1 was carried out in a sample of 561 unrelated Chinese Han individuals using oligonucleotide arrays for genotype detection. Meanwhile, we explored the feasibility of typing HLA-DRB1 by DNA chip for forensic identification.


RESULTS
No significant deviations from Hardy-Weinberg equilibrium could be found. The Observed heterozygosity(Ho) was 0.888. The Expected heterozygosity (He) was 0.902. The Polymorphic information content (PIC) was 0.893. The Average exclusion probability (PE) was 0.801. Pedigree analysis showed no deviation from Mendel's Law.


CONCLUSIONS
The data and results of pedigree analysis and case application demonstrated that HLA-DRB1 typing by oligonucleotide probe arrays was a useful technique for paternity testing and individual identification.
