Abstract
This study evaluates the incidence and prognostic impact of aberrant methylation of 25 tumor suppressor genes in 40 patients with RARS, a MDS subtype, by methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) assay. Methylation of at least one gene was detected in 18 patients (45%). The genes methylated were CDKN2B (20%), RASSF1 (18%), RARB (10%), CDH13 (7.5%) and FHIT (5%). Patients with at least one methylated gene had a significantly shorter OS than patients without methylated genes. Aberrant methylation is a frequent event in patients with RARS as in patients with high-risk MDS appears to confer a worse prognosis. (c) 2010 Elsevier Ltd. All rights reserved.
