Abstract:
Polymalformative syndromes are always a clinical challenge for their complexity and sometimes for their rarity. Authors present the case of a girl with peculiar facies, macrocephaly, axial hypotonia, and severe development delay. Cerebral magnetic resonance showed polymicrogyria. Cytogenetics revealed a 46,XX,der(1)(qter-->p36.13::q42.3-->qter) karyotype. This is the third case described to date. Isolated partial deletions or trisomy, although rare, are more frequently reported. None of these genetic findings has ever been related with polymicrogyria. Molecular cytogenetic characterization was in this case of great value.
