An 18-year-old female with mild mental disability (global IQ 69), febrile seizures with subsequent myoclonic/grand mal epilepsy, and subtle morphologic changes is described with del 5(q14.3q21.3) by karyotype and minimal DNA deletion of 21.08 Mb by array comparative genomic hybridization microarray analysis (arr chr5:83,592,798-104,671,993 X1) that encompasses at least 50 genes. Included in the deletion interval is the MEF2C gene that usually causes severe mental disability when haploinsufficient, illustrating the complexity of clinic-cytogenetic correlation even with defined segmental aneuploidy. Interaction of MEF2C with the deleted febrile seizure (FEB4) and juveline myoclonic epilepsy (EJM4) loci plus the G-protein receptor (GPR98/MASS1/Usher syndrome) gene may moderate the phenotype, perhaps through common regulation by calcium.

Genetic screening is being widely applied to trace the origin of global developmental delay or intellectual disability. The 5q14.3 microdeletion has recently been uncovered as a clinical syndrome presenting with severe intellectual disability, limited walking ability, febrile convulsions, absence of speech, and minor brain malformations. MEF2C was suggested as a gene mainly responsible for the 5q14.3 microdeletion syndrome. We present the case of a 6-year-old girl, who is the first patient in Korea with de novo interstitial microdeletions involving 5q14.3, showing the typical clinical features of 5q14.3 microdeletion syndrome with a smaller size of chromosomal involvement compared to the previous reports. The microdeletion was not detected by subtelomeric multiplex ligation-dependent probe amplification, but by array comparative genomic hybridization, which is advisable for the detection of a small-sized genetic abnormality.
