Summaries for Cerebroretinal Microangiopathy with Calcifications and Cysts 2

UniProtKB/Swiss-Prot : 76 Cerebroretinal microangiopathy with calcifications and cysts 2: An autosomal recessive, multisystemic disorder characterized by intrauterine growth retardation and, later in life, premature aging symptoms, including poor growth, graying hair, liver fibrosis, portal hypertension, esophageal varices, osteopenia, pancytopenia, hypocellular bone marrow, and vascular telangiectasia resulting in gastrointestinal bleeding. Brain calcifications and white matter changes are responsible for signs including spasticity, ataxia, or dystonia observed in some patients.

MalaCards based summary : Cerebroretinal Microangiopathy with Calcifications and Cysts 2, is also known as crmcc2. An important gene associated with Cerebroretinal Microangiopathy with Calcifications and Cysts 2 is STN1 (STN1 Subunit Of CST Complex). Affiliated tissues include bone, brain and liver, and related phenotypes are osteopenia and ataxia

OMIM : 58 CRMCC2 is an autosomal recessive multisystem disorder characterized by premature aging, pancytopenia, hypocellular bone marrow, osteopenia, liver fibrosis, and vascular telangiectasia resulting in gastrointestinal bleeding. Brain imaging shows intracranial calcifications and leukodystrophy, which may result in neurologic signs including spasticity, ataxia, or dystonia. Patients may also have retinal telangiectasia (summary by Simon et al., 2016). For a discussion of genetic heterogeneity of CRMCC, see CRMCC1 (612199). (617341)
