  • nucleic acid encompasses nucleic acid molecules of both natural and synthetic origin as well as molecules of linear, circular or branched configuration representing either the sense or antisense strand, or both, of a native nucleic acid molecule.

  • Use of the polymerase chain reaction for the amplification of nucleic acids is well known in the art (8).
  • a TaqmanB allelic discrimination assay available from Applied Biosystems may be useful for determining the presence or absence of a variant allele.

  • the probes contain different fluorescent reporter dyes such as FAM and VICTM to differentiate the amplification of each allele.
  • each probe has a quencher dye at one end which quenches fluorescence by fluorescence resonant energy transfer (FRET).
  • FRET fluorescence resonant energy transfer
  • each probe anneals specifically to complementary sequences in the nucleic acid from the individual.
  • the 5' nuclease activity of Taq polymerase is used to cleave only probe that hybridize to the allele.
  • Cleavage separates the reporter dye from the quencher dye, resulting in increased fluorescence by the reporter dye.
  • the fluorescence signal generated by PCR amplification indicates which alleles are present in the sample.
  • Mismatches between a probe and allele reduce the efficiency of both probe hybridization and cleavage by Taq polymerase, resulting in little to no fluorescent signal.
  • Improved specificity in allelic discrimination assays can be achieved by conjugating a DNA minor grove binder (MGB) group to a DNA probe as described, previously (9).
  • Minor grove binders include, but are not limited to, compounds such as dihydrocyclopyrrolo indole tripeptide (DPI).
  • Restriction fragment length polymorphism (RFLP) analysis may also be useful for determining the presence or absence of a particular allele (10-11).
  • restriction fragment length polymorphism analysis is any method for distinguishing genetic polymorphisms using a restriction enzyme, which is an endonuclease that catalyzes the degradation of nucleic acid and recognizes a specific base sequence, generally a palindrome or inverted repeat.

  • Allele-specific oligonucleotide hybridization may also be used to detect a disease- predisposing allele. Allele-specific oligonucleotide hybridization is based on the use of a labeled oligonucleotide probe having a sequence perfectly complementary, for example, to the sequence encompassing a disease-predisposing allele. Under appropriate conditions, the allele-specific probe hybridizes to a nucleic acid containing the disease-predisposing allele but does not hybridize to the one or more other alleles, which have one or more nucleotide mismatches as compared to the probe. If desired, a second allele-specific oligonucleotide probe that matches an alternate allele also can be used.
  • the technique of allele-specific oligonucleotide amplification can be used to selectively amplify, for example, a disease-predisposing allele by using an allele-specific oligonucleotide primer that is perfectly complementary to the nucleotide sequence of the disease-predisposing allele but which has one or more mismatches as compared to other alleles (8).
  • an allele-specific oligonucleotide primer that is perfectly complementary to the nucleotide sequence of the disease-predisposing allele but which has one or more mismatches as compared to other alleles (8).
  • the one or more nucleotide mismatches that distinguish between the disease-predisposing allele and one or more other alleles are preferably located in the center of an allele-specific oligonucleotide primer to be used in allele-specific oligonucleotide hybridization.
  • an allele-specific oligonucleotide primer to be used in PCR amplification preferably contains the one or more nucleotide mismatches that distinguish between the disease-associated and other alleles at the 3 ' end of the primer.
  • HMA heteroduplex mobility assay
  • SSCP single strand conformational, polymorphism
  • This technique can be used to detect mutations based on differences in the secondary structure of single-strand DNA that produce an altered electrophoretic mobility upon non-denaturing gel electrophoresis. Polymorphic fragments are detected by comparison of the electrophoretic pattern of the test fragment to corresponding standard fragments containing known alleles.
  • Denaturing gradient gel electrophoresis also may be used to detect a SNP and/or a haplotype.
  • DGGE Denaturing gradient gel electrophoresis
  • double-stranded DNA is electrophoresed in a gel containing an increasing concentration of denaturant; double- stranded fragments made up of mismatched alleles have segments that melt more rapidly, causing such fragments to migrate differently as compared to perfectly complementary sequences (11).
  • CD subjects of mixed Caucasian ethnicity and 3970 controls from the Cardiovascular Health Study were geno typed, using Illumina technology (Human 610Quad, Human 317Duo or the HumanCNV370-Duo platform). 234,637 SNPs were available for analyses in all datasets. Multidimensional Scaling was used to detect population substructure. Ten principal components were calculated and principal components 1 and 2 were plotted to generate informative cluster plots for ethnicity. Self-reported ethnicity in CD cases was used to confirm the Ashkenazi Jewish "cluster" and select cases and controls ethnically matched by principal components. Association with case/control status was performed using a logistic regression model.
  • the inventors identified 247 Ashkenazi Jewish CD cases and 320 ethnically matched controls by principal components. Genomic inflation was calculated at ⁇ . ⁇ . A Q-Q plot of P values showed a modest increase of significant associations above the expected under the null hypothesis.
