What research have we done on StrateGene

Does StrateGene Run Core SNPs in Triplicates?

Yes, at StrateGene we run our core SNPs triplicate to achieve higher quality call rates. Please read our FAQ on Which Factors Can Influence My DNA Results.

Why are the reference alleles different from what I see in the literature, for example, A for T or C for G for MTHFR C677T?

Alleles are listed in the DNA plus orientation, AKA positive strand orientation as reported by the Illumina array utilized. The positive DNA strand orientation is by convention read from 5' → 3' direction. The minus or negative orientations is 3' → 5

How exact is the information regarding kinetics and a variant?

Even though a precise number taken from research is listed for a particular variant, in the real world these numbers should be considered approximations.

Are their other ways genes can mutate besides SNPs?

Genetic code can be "misspelled" in many ways besides a single nucleotide polymorphism. These include deletions, copy repeats, gain, loss, or inversion mutations among others. The StrateGene test cannot detect most of these more complicated structura

How did you determine which SNPs to include?

We have decided to only include those SNPs for which we felt there was compelling evidence-based research involving human subjects. One study alone would not necessarily suffice for inclusion, just as many studies regarding a particular SNP may not h

Are there other ways genes can mutate besides SNPs?

Yes, genetic code can be "mis-spelled" many ways besides a single nucleotide polymorphism. These include deletions, copy repeats, gain, loss, or inversion among others. You can read more here: http://www.ncbi.nlm.nih.gov/dbvar/content/overview/ .

What specific types of evidence did you look at when determining which SNPs to include?

We considered the following types of research:. EBIV: Evidence Based in vitro. EBinvivo: Evidence Based in vivo. EBCC: Evidence based case controlled study. EBCR: Evidence based case report. EBCS: Evidence based cohort study. EBCX: Evidence based cro

What is CEU?

CEU aka CEPH is an acronym for Utah Residents with Northern and Western European Ancestry. These samples were collected from people living in Utah with ancestry from northern and western Europe. The term "CEPH" stands for the Centre d'Etude du Polymo

What if I work with patients, or I am largely of different racial background than CEU and I want to determine the frequency of an allele?
