Résumé
Here we describe the clinical, histopathological and molecular studies of a female proband that died at 2 months of age in the context of a syndromic polymicrogyria. There was no significant family history. Clinical and radiological features included poor contact, cleft palate, facial dysmorphic features with frontal bossing, down-slanting and small palpebral fissures, inferior epicanthic folds, low-set and malformed ears, flat nose, retrognathism and short neck, minor limb anomalies, polymicrogyria that appear more severe in the perisylvian regions and cerebellar vermis hypoplasia. Autopsy findings revealed a patent foramen ovale with persistent left superior vena cava, left renal hypoplasia and microphthalmia. This description does not fit with any of the known syndromes with polymicrogyria and cytogenetic analyses including standard and high resolution chromosome analyses, telomeric FISH studies and array-CGH were normal. Consequently, the reported features in this child are unique and are likely to represent a new syndrome.
