Summaries for Aicardi-Goutieres Syndrome 7

OMIM® : 57 Aicardi-Goutieres syndrome-7 (AGS7) is an autosomal dominant inflammatory disorder characterized by severe neurologic impairment. Most patients present in infancy with delayed psychomotor development, axial hypotonia, spasticity, and brain imaging changes, including basal ganglia calcification, cerebral atrophy, and deep white matter abnormalities. Laboratory evaluation shows increased alpha-interferon (IFNA1; 147660) activity with upregulation of interferon signaling and interferon-stimulated gene expression. Some patients may have normal early development followed by episodic neurologic regression (summary by Rice et al., 2014). For a phenotypic description and a discussion of genetic heterogeneity of Aicardi-Goutieres syndrome, see AGS1 (225750). (615846) (Updated 05-Mar-2021)

MalaCards based summary : Aicardi-Goutieres Syndrome 7, is also known as ags7. An important gene associated with Aicardi-Goutieres Syndrome 7 is IFIH1 (Interferon Induced With Helicase C Domain 1). Affiliated tissues include eye, and related phenotypes are abnormality of eye movement and developmental regression

UniProtKB/Swiss-Prot : 73 Aicardi-Goutieres syndrome 7: 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.
