We here report a boy presenting with developmental delay, growth retardation, facial dysmorphisms, vermis hypoplasia, micropolygyria and corpus callosum agenesis. Conventional and high resolution cytogenetic analyses were normal but high resolution oligonucleotide array-CGH, performed at the age of 4 years, allowed the characterisation of a de novo 6.9 Mb 1qter deletion/4.4 Mb 18pter duplication. Numerous 1qter deletions have already been described associated with brain malformations. Among 1q44 deleted genes, AKT3 is the strongest candidate gene for vermis hypoplasia and corpus callosum agenesis.
