GISNP9K Forensic Genealogy Inference Kit
In collaboration with the Beijing Forensic Science and Technology Co. Ltd, FGI developed the GISNP9K Forensic Genealogy Inference Kit that detects 9858 SNPs using liquid-phase hybridization capture sequencing technology. It performs genotype and kinship inference testing based on BGI high-throughput sequencing platform. Based on FGI self-developed algorithm and data analysis software, it can accurately infer 1-5 kinship degrees. Moreover, the kit is capable of interpreting the Y-SNP haplotype, mtDNA maternal lineage tracing, blood type, gender determination, eye color, hair color and skin pigmentation.

l Comprehensive: simultaneous detection of 9858 SNPs in one run, including those from autosomes, Y-chromosome, mitochondria, etc.
l Powerful Practical Functionality: genealogy inference, maternal kinship, paternal lineage, individual identification, phenotype, blood type, etc. Enables multidimensional interpretation of data.
l Cost-effective: small data throughput for each sample, increased number of samples per run.
Technical Principle
Forensic Genealogy Inference Technology is usually defined as the analysis of high density autosomal SNP information obtained from biological samples to infer the degree of kinship between selected individuals. The degree of kinship is a parameter of how related of one individual to another. Higher degrees suggest more distant kinship ties. For immediate family members, degree of kinship equals to the number of meiotic events. For half-siblings, the degree of kinship is the sum of meiotic events of the common ancestor. For full-siblings, the degree of kinship is the sum of meiotic events of the common ancestor subtracted by 1.
FGID Forensic DNA Analysis System
FGID Forensic DNA Analysis System is a massively-parallel sequencing solution developed based on the standard of bioinformatic analysis, which is used in the large-scale analysis of high-frequency single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs). This system is totally compatible with BGI high throughput sequencing platform, providing a one-stop solution starting from the output FASTQ data to the genotyping report or identification report. The system consists of 6 main functional modules: configuration center, sample center, task center, analysis center, report center and identification center. The analysis functions include genotype difference, individual identification, complex kinship, genealogy interpretation, ancestry, etc.
