Summaries for Aicardi-Goutieres Syndrome 4

NIH Rare Diseases : 54 Aicardi-Goutieres syndrome is an inherited disease that mainly affects the brain, immune system, and the skin. Loss of white matter in the brain (leukodystrophy) and abnormal deposits of calcium (calcification) in the brain leads to an early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability.  Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint and muscle stiffness (spasticity), involuntary muscle twisting and contractions (dystonia), and weak muscle tone (hypotonia) in the torso. Other signs and symptoms may include a very small head (microcephaly), presence of white blood cells and other sign of inflammation in the  cerebrospinal fluid, which is the fluid that surrounds the brain and spinal cord (central nervous system). Symptoms usually progress over several months before the disease course stabilizes.  There are several types of Aicardi-Goutieres syndrome, depending on the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR and IFIH1, genes. Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive. The prognosis depends mainly on the severity neurologic problems and in the age of onset of these problems.

MalaCards based summary : Aicardi-Goutieres Syndrome 4, also known as ags4, is related to pseudo-torch syndrome 1 and pseudo-torch syndrome 2, and has symptoms including seizures, muscle spasticity and petechiae of skin. An important gene associated with Aicardi-Goutieres Syndrome 4 is RNASEH2A (Ribonuclease H2 Subunit A). Affiliated tissues include skin, brain and spinal cord, and related phenotypes are low-set ears and hydrocephalus

UniProtKB/Swiss-Prot : 76 Aicardi-Goutieres syndrome 4: A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood.
