Summaries for Pseudo-Torch Syndrome 2

OMIM : ⁵⁸ Pseudo-TORCH syndrome-2 is an autosomal recessive multisystem disorder characterized by antenatal onset of intracranial hemorrhage, calcification, brain malformations, liver dysfunction, and often thrombocytopenia. Affected individuals tend to have respiratory insufficiency and seizures, and die in infancy. The phenotype resembles the sequelae of intrauterine infection, but there is no evidence of an infectious agent. The disorder results from inappropriate activation of the interferon (IFN) immunologic pathway (summary by Meuwissen et al., 2016). For a discussion of genetic heterogeneity of PTORCH, see PTORCH1 (251290). (617397)

MalaCards based summary : Pseudo-Torch Syndrome 2, also known as ptorch2, is related to aicardi-goutieres syndrome 2 and aicardi-goutieres syndrome 3. An important gene associated with Pseudo-Torch Syndrome 2 is USP18 (Ubiquitin Specific Peptidase 18). Affiliated tissues include brain and bone, and related phenotypes are seizures and elevated hepatic transaminase
