There is provided a system performing high-accuracy diagnostic decision support in consideration of the influence of a haplotype block and a genetic structure.

Haplotype block inference means 13 infers the positions of haplotype blocks, and analyzes each of the haplotype blocks to infer a haplotype pattern of individuals with high accuracy. Genetic structure inference means 15 performs clustering the individuals on the basis of the haplotype pattern to divide a population into some subpopulations, and removes the influence of a genetic structure existing in the population. A genetic structure information database 16 and a clinical information database 11 are used to analyze association of clinical information with genetic information for providing high-accuracy diagnostic decision support knowledge. On the basis of the diagnostic decision support knowledge obtained by analyzing the association of clinical information with genetic information, risk calculation means 19 calculates a risk that a predetermined individual is affected by disease.

The invention discloses a restrictive two-stage genome-wide association study (GWAS) method based on an SNPLDB mark, and aims at solving the problems that a traditional method cannot be used for estimating multiple allele information, and is high in false positive rate and low in efficiency of detection on inbreeding crops. By combination of the SNPLDB mark constructed on the basis of a haplotype block, correction of deviation of an inbreeding population relation analysis model and a two-stage relation analysis strategy under a multi-site model, the GWAS method suitable for conventional breeding of inbreeding crops is built; the SNPLDB mark is applied to GWAS, so that a method is provided for multiple allele estimation; candidate sites are screened on the basis of a single-site model in the first stage, and are further screened on the basis of a progressive regression analysis method in the multi-site model in the second stage, so as to balance the problems of missing of heritability and over-high heritability estimation. Therefore, the interpretation ratio of a final genetic model is controlled at trait heritability. The positioning accuracy and efficiency are improved by a feature vector and an appropriate significant level of a similarity coefficient matrix estimated by the SNPLDB mark by GWAS.

We have identified and isolated a 12 kb region immediately upstream of the AKT1 gene containing eight single nucleotide polymorphic polynucleotides (SNPs) in 4 haplotype regions that show strong association with body composition, Basal Mass Index, and AKT1 expression enhancement in human males. A four-locus haplotype (Haplotype 2) was defined where residues within highly conserved regulatory regions were altered. This haplotype explained up to 26% of population variation in bone cortical volume, 12% of subcutaneous fat volume, and 9% of strength variation, resulting in a body build with large bones, strong muscles, and low subcutaneous fat. Other SNPs detect, presymptomatically, the potential for increased amounts of subcutaneous fat and Type II diabetes. The detection of these SNPs by the techniques described herein forms the foundation for genotype-specific clinical interventions designed to slow the rapid population increases in obesity and Type II diabetes.

A genetic polymorphism and a hair shape susceptibility gene that are related to hair shape, and a method for determining the genetic susceptibility to hair shape in individual test subjects are provided. Disclosed is a hair shape susceptibility gene, which overlaps with a haplotype block in the 1q32.1 to 1q32.2 region (D1S249 to D1S2891) of human chromosome 1 and comprises a portion or the entirety of the base sequence of the haplotype block, wherein the haplotype block is determined by a linkage disequilibrium analysis conducted on a single nucleotide polymorphism (SNP) marker whose allele frequency differs statistically significantly between a group having a curly hair trait and a group having a non-curly hair trait, and consists of a base sequence set forth in any one of SEQ ID NO:1 to NO:3.

A numerical approach used to select a reduced subset of single nucleotide polymorphisms (SNPs) from a larger superset and useful for efficiently identifying haplotype blocks or other genetic loci. In general, the methods may be configured to select for the reduced SNP subset with little or no loss of haplotype diversity information. The methods may also be adapted to operate in a more aggressive mode to further reduce the SNP set while maintaining diversity of haplotype blocks with minimal loss of information. Computation of the reduced SNP subset is generally rapid and the methods perform well even when applied to large data sets spanning significant genomic distances.

The invention relates to a set of single nucleotide polymorphism (SNP), a biological marker and haplotype block tag single nucleotide polymorphisms (tagSNPs) for diagnosing hyperbilirubinemia in the technical field of biology. An SNP locus is one of the fifteen SNP loca shown in a table, and the biological marker is 1A4 intron SNPc.867+101G>T. The set of the SNP, the biological marker and the haplotype block tagSNPs can detect whether an individual has the risk of diseases or not, diagnose specific types of the hyperbilirubinemia suffered by the individual according to difference of the SNP loca of a specific marker, and achieve the purposes of early prediction, early diagnosis, early intervention and early treatment. The biological marker can further be used for developing a diagnostic reagent kit and can be applied to clinical research, analysis and diagnosis.
