Abstract:
We report a 19-month-old boy with microcephaly, growth and developmental delay, facial dysmorphisms, and simplified gyral pattern. Magnetic resonance imaging (MRI) examination demonstrated microcephaly with simplified gyral pattern or oligogyric microcephaly. The facial phenotype was interpreted as suggestive of Williams syndrome (WS). Fluorescence in situ hybridization (FISH) analysis performed with an elastin probe revealed a deletion in the chromosomal band 7q 11.23, confirming the clinical diagnosis. To our knowledge, this represents the first patient with WS and oligogyric microcephaly.
