LEUKOENCEPHALOPATHY, BRAIN CALCIFICATIONS, AND CYSTS; LCC

Alternate names

LEUKOENCEPHALOPATHY, BRAIN CALCIFICATIONS, AND CYSTS; LCC Is also known as labrune syndrome

Description

Leukoencephalopathy, brain calcifications, and cysts (LCC), also known as Labrune syndrome, is characterized by a constellation of features restricted to the central nervous system, including leukoencephalopathy, brain calcifications, and cysts, resulting in spasticity, dystonia, seizures, and cognitive decline (summary by Labrune et al., 1996).See also cerebroretinal microangiopathy with calcifications and cysts (CRMCC ), an autosomal recessive disorder caused by mutation in the CTC1 gene (OMIM ) that shows phenotypic similarities to Labrune syndrome. CRMCC includes the neurologic findings of intracranial calcifications, leukodystrophy, and brain cysts, but also includes retinal vascular abnormalities and other systemic manifestations, such as osteopenia with poor bone healing, a high risk of gastrointestinal bleeding, hair, skin, and nail changes, and anemia and thrombocytopenia. 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).
