Additional Information:
Description: (OMIM) |
Van Maldergem syndrome is an autosomal recessive disorder characterized by intellectual disability, typical craniofacial features, auditory malformations resulting in hearing loss, and skeletal and limb malformations. Some patients have renal hypoplasia. Brain MRI typically shows periventricular nodular heterotopia ... |
Clinical Description OMIM |
Mansour et al. (2012) reported 2 unrelated patients (patients 1 and 6) with Van Maldergem syndrome-2. The patients had a distinctive facial appearance that included large fontanels, maxillary hypoplasia, micrognathia, flat face, blepharophimosis, telecanthus, broad nasal bridge, and ... |
Molecular genetics OMIM |
In 5 patients from 4 unrelated families with Van Maldergem syndrome-2, Cappello et al. (2013) identified biallelic mutations in the FAT4 gene (612411.0001-612411.0006). The first mutations were found by whole-exome sequencing and the subsequent mutations were found by ... |
