A case of Baraitser-Winter syndrome with unusual brain MRI findings: pachygyria, subcortical-band heterotopia, and periventricular heterotopia.
Baraitser-Winter syndrome (BaWS) is characterized by iris coloboma, ptosis, hypertelorism, and mental retardation; it is a rare multiple congenital anomaly or a mental-retardation syndrome of unknown etiology. Patients suffering from this syndrome have been also found to show brain anomalies such as pachygyria, subcortical-band heterotopia (SBH), and hippocampal malformations; therefore, these anomalies have been included in the phenotypic spectrum of this syndrome. We report the case of a Japanese boy suffering from BaWS; the patient's brain magnetic resonance imaging scan revealed pachygyria, SBH, and periventricular heterotopia. However, the results of the genome-wide array comparative genomic hybridization did not reveal any chromosomal rearrangements.
