Summaries for Cerebroretinal Microangiopathy with Calcifications and Cysts 1

OMIM : 58 Cerebroretinal microangiopathy with calcifications and cysts (CRMCC), also known as Coats plus syndrome, is an autosomal recessive pleomorphic disorder characterized primarily by intracranial calcifications, leukodystrophy, and brain cysts, resulting in spasticity, ataxia, dystonia, seizures, and cognitive decline. Patients also have retinal telangiectasia and exudates (Coats disease) as well as extraneurologic manifestations, including osteopenia with poor bone healing and a high risk of gastrointestinal bleeding and portal hypertension caused by vasculature ectasias in the stomach, small intestine, and liver. Some individuals also have hair, skin, and nail changes, as well as anemia and thrombocytopenia (summary by Anderson et al., 2012 and Polvi et al., 2012). Leukoencephalopathy, brain calcifications, and cysts (LCC), also known as Labrune syndrome (614561), has similar central nervous system features as CRMCC in the absence of extraneurologic or systemic manifestations. Although Coats plus syndrome and Labrune syndrome were initially thought to be manifestations of the same disorder, namely CRMCC, molecular evidence has excluded mutations in the CTC1 gene in patients with Labrune syndrome, suggesting that the 2 disorders are not allelic (Anderson et al., 2012; Polvi et al., 2012). Some features of CRMCC resemble those observed in dyskeratosis congenita (see, e.g., 127550), which is a clinically and genetically heterogeneous telomere-related genetic disorder. (612199)

MalaCards based summary : Cerebroretinal Microangiopathy with Calcifications and Cysts 1, also known as cerebroretinal microangiopathy with calcifications and cysts, is related to htra1-related autosomal dominant cerebral small vessel disease and leukoencephalopathy, brain calcifications, and cysts, and has symptoms including seizures, ataxia and tremor. An important gene associated with Cerebroretinal Microangiopathy with Calcifications and Cysts 1 is CTC1 (CST Telomere Replication Complex Component 1). Affiliated tissues include bone, brain and skin, and related phenotypes are bone marrow hypocellularity and thrombocytopenia

Genetics Home Reference : 26 Coats plus syndrome is an inherited condition characterized by an eye disorder called Coats disease plus abnormalities of the brain, bones, gastrointestinal system, and other parts of the body.
