Gomez-Lopez-Hernandez syndrome is a very rare genetic disorder with a distinct phenotype (OMIM 601853). To our knowledge there have been seven cases documented to date. We report on an additional male patient now aged 15 8/12 years with synostosis of the lambdoid suture, partial scalp alopecia, corneal opacity, mental retardation and striking phenotypic features (e.g., brachyturricephaly, hypertelorism, midface hypoplasia and low-set ears) consistent with Gomez-Lopez-Hernandez syndrome. In early childhood the patient demonstrated aggressive behavior and raging periods. He also had seizures that were adequately controlled by medication. Magnetic resonance imaging (MRI) revealed rhombencephalosynapsis, i.e., a rare fusion of the cerebellar hemispheres, also consistent with Gomez-Lopez-Hernandez syndrome. In addition a lipoma of the quadrigeminal plate was observed, a feature not previously described in the seven patients reported in the literature. Cytogenetic and subtelomere analyses were inconspicuous. Microarray-based comparative genomic hybridization (array-CGH) testing revealed five aberrations (partial deletions of 1p21.1, 8q24.23, 10q11.2, Xq26.3 and partial duplication of 19p13.2), which, however, have been classified as normal variants. Array-CGH has not been published in the previously reported children. The combination of certain craniofacial features, including partial alopecia, and the presence of rhombencephalosynapsis in the MRI are suggestive of Gomez-Lopez-Hernandez syndrome. Children with this syndrome should undergo a certain social pediatric protocol including EEG diagnostics, ophthalmological investingation, psychological testing, management of behavioral problems and genetic counseling.
