disease_ontology

Wolf-Hirschhorn syndrome results from the partial deletion of the short arm of chromosome 4. The abnormality results in developmental delay, intellectual impairment (severe), hypotonia and epilepsy, and a number of dysmorphic features (microcephaly, micrognathia, short philtrum, epicanthic folds, high forehead, prominent glabella, ocular hypertelorism, dysplastic ears and peri-auricular tags). The nose may have a 'Greek helmet' appearance. There may also be congenital heart defects, hypospadias, colobomata of the iris, renal anomalies, cleft lip and/or palate and deafness. Immune disorders including common variable immunodeficiency and IgA deficiency may occur. Neuroimaging may show abnormalities of the corpus callosum or cerebellum, or other abnormality. Most cases are sporadic, with 10% inherited from a parent with a translocation. Seizures occur in the majority (>90%), typically starting in the first three years of life, with generalized tonic-clonic or hemiclonic seizures facilitated by fever (resulting in seizure clusters or status epilepticus) seen at that time. Epileptic spasms, atypical absences and focal seizures may also occur. EEG patterns of two types are recognized - diffuse, atypical slow sharp/spike-and-wave complexes in long bursts activated by slow wave sleep or high amplitude fast spike/polyspike-and-wave with posterior emphasis, triggered by eye closure. Seizures are usually well-controlled with monotherapy and improve with age. Routine karyotype assessment may not allow diagnosis of this syndrome, FISH analysis with sub-telomeric region-specific probes or CGH microarray are usually necessary.
