Abstract:
We report a 4-year-old Turkish boy with Warburg Micro syndrome born to consanguineous parents. He had ptosis, deep-set eyes, microphthalmia, microcornea, microcephaly, prominent ears and nasal root, micrognathia, hypertrichosis, spastic diplegia, skin hyperextensibility and joint hypermobility, hypogenitalism, cerebral atrophy and hypoplasia of corpus callosum and cerebellum. Sequence analysis of exon 8 of the RAB3GAP gene has confirmed the presence of a splice donor mutation (748+1G>A) in the homozygous state. Skin hyperextensibility and joint hypermobility in the affected child have not been reported in Warburg Micro syndrome cases to date. This report compares the symptoms and features of the case with previously reported cases of Warburg Micro syndrome.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
