Microarray based mutational analysis of patients with methylmalonic acidemia: Identification of 10 novel mutations

► Microarray based mutation screening was performed. ► 30 Turkish patients diagnosed with mut MMA were included in the study. ► 22 different mutations, 10 of which are novel, were detected. ► The most common p.P615T mutation was identified in 28% of patients. ► Microarray sequencing is a useful tool for mutation screening in MUT gene.
