Using whole genome expression microarray technology to discover clinically relevant biomarkers for pilocytic astrocytoma (PA), the authors identified matrilin-2 as a unique mRNA overexpressed in PA. Matrilin-2 protein expression was similarly elevated in the majority of sporadic PA, but in only one neurofibromatosis 1-associated PA with an unusually aggressive clinical phenotype. These results suggest that matrilin-2 may be a specific and clinically useful biomarker for discriminating between indolent and clinically aggressive PA.
