Description : 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;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the conserved telomere maintenance component 1 gene (CTC1, 613129.0001);
Laboratory abnormalities : Shortened telomeres;
