CAMMARATA-SCALISI, Francisco et al. Wolf-Hirschhorn syndrome: Description of five cases characterized by means of single nucleotide polymorphism microarrays. Arch. argent. pediatr. [online]. 2019, vol.117, n.4, pp.e406-e412. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2019.e406.

Wolf-Hirschhorn syndrome is a polymalformative entity due to the microdeletion in the distal region of the short arm of chromosome 4 (4p16.3), which produces a series of clinical manifestations that can vary depending on the type and size of the genetic defect in this contiguous gene syndrome. Five patients are presented, three of them female, all with the primary clinical findings, characterized by "Greek warrior helmet appearance" facial feature, growth retardation and psychomotor development delay. In addition to the partial deletion in the distal region of the short arm of chromosome 4, two additional genetic alterations were found in two patients, through the use of single nucleotide polymorphism arrays. The clinical characteristics of Wolf-Hirschhorn syndrome are highlighted in order to guide the diagnosis, provide interdisciplinary medical care and, through its confirmation, provide adequate family genetic counseling.
