Researchers from St. Jude Children's and the German Cancer Research Center used methylation and gene expression analyses to uncover the subtypes.
The approach can increase CpG coverage about 18-fold by inferring from existing data to predict methylation of sites outside those covered on the arrays themselves.
The researchers said that the methylation mark could potentially be used as a noninvasive biomarker for certain tumor types.
The company presented its findings last week at the 2016 Gastrointestinal Cancer Symposium and is preparing to launch the assay in the US later this year.
