Abstract:
:The 17q21.31 microdeletion syndrome is a genetic disorder characterized by intellectual disability, facial dysmorphisms and a typical behavioral phenotype. Patients are usually described as friendly and cooperative but they can also show behavioral problems such as hyperactivity, bad humor, temper tantrums and poor interaction. Central nervous system involvement includes callosal dysgenesis/absence, enlargement of lateral ventricles and abnormalities of cyngulate gyrus. We report on two Italian patients with the 17q21.31 microdeletion syndrome better emphasizing neuroimaging and neuropsychological characteristics. In particular, we carried out an assessment of intellectual efficiency and behavior that turned out to be within the mild-moderate range of mental retardation, as already reported in the literature. To the best of our knowledge this is the first report of a patient with the 17q21.31 microdeletion and a Chiari malformation type 1 coexisting with a mild anomaly of medulla oblongata. This malformation should be considered in patients with the 17q21.31 microdeletion syndrome, presenting suggestive symptoms (headache, neck pain, cerebellar signs or muscle weakness).
