We present four patients, in whom we identified overlapping deletions in 5q14.3 involving MEF2C using a clinical oligonucleotide array comparative genomic hybridization (CGH) chromosomal microarray analysis (CMA). In case 1, CMA revealed an ∼140 kb deletion encompassing the first three exons of MEF2C in a 3‐year‐old patient with severe psychomotor retardation, periodic tremor, and an abnormal motor pattern with mirror movement of the upper limbs observed during infancy, hypotonia, abnormal EEG… Expand
