October 14, 2014. New paper in press on the epigenetics of metaphase chromosomes

Oct 17, 2014   //   by Peter Rogan   //   News  //  Comments Off

Using our patented ab initio scFISH probes, Cytognomix and Western University researchers have discovered important differences between paired chromosomes. No other product on the market can detect these chromosome features. The following article has been accepted for publication in a leading open access journal:

Khan W, Rogan PK, and Knoll JHM. Localized, Non-random Differences in Chromatin Accessibility between Homologous Metaphase Chromosomes, Mol. Cytogenetics, in press.

Stay tuned for the URL of the published paper. It should be available shortly!

May 23, 2014. A Comment about Variant Databases

May 24, 2014   //   by Peter Rogan   //   News  //  Comments Off

Variant databases are an essential resource for both clinical and research genomics. Has the variant been reported previously in a patient and if so, what was their phenotype? They are used to exclude benign or common variants as pathogenetic, based on their high frequency in asymptomatic individuals. Many researchers curate variant databases of specific loci, regularly contribute known and new to public databases, and several companies release products aimed at compiling and visualizing this data. Determining the frequency and recurrence of variants can only be done through this compilation procedure.  Clinical labs maintain their own databases and regularly query public and commercial variant repositories to make sense of newly generated sequencing findings. Of course, it’s a lot easier to write up a variant if all one has to do is look it up in a database.

There is a fundamental problem with this approach: in a genome of 3.2 billion nucleotides, there are an infinite number of  possible mutations (single and oligo nucleotide changes on each chromosome). There is no database in existence that can catalog all of these effects, nor predict these effects based on prior knowledge of all of the mutation combinations. Only computational modeling of sequence variant effects can possibly provide a means of evaluting newly discovered mutations without explicit reference to a database of prior variants.  The approaches that Cytognomix has developed complement existing databases by confirming evidence of selection against predicted pathogenic variants (low allele frequencies), but more importantly, can predict deleterious effects when the mutation has not been observed previously.
