The syndrome is associated with intellectual disability, low muscle tone (hypotonia), characteristic facial features, constipation, Hirschsprung disease (an intestinal condition), epilepsy, short stature, small head (microcephalus) as well as malformations of the heart, brain, genitals, urinary tract and eyes.
An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum , from very-low-frequency ( VLF ) radio to ultraviolet ( UV ) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires.
Immune thrombocytopenia (ITP) is an acquired form of thrombocytopenia due to autoantibody-mediated destruction of platelets. The autoantibodies also affect megakaryocytes and impair platelet production. ITP is a diagnosis of exclusion, characterized by isolated thrombocytopenia and the lack of a clinically-apparent condition responsible for the low platelet count; there are no reliable laboratory tests to confirm the diagnosis.
