In this report we describe a 10 year-old female patient with interstitial deletion of 9q32-q34.1 associated with mental retardation, developmental delay, short stature, mild facial dysmorphism, epilepsy, abnormal EEG and brain MRI findings consistent with focal cortical dysplasia. Interstitial deletion of 9q associated with q32-q34 is found extremely rare. Common features of seven previously reported cases are mental retardation, developmental delay, short stature, a distinct cranial and facial phenotype (brachycephaly, low midface, low and prominent forehead, and low set malformed ears). Combination of epilepsy, abnormal EEG and brain MRI findings are not reported before.
