Summaries for Primary Familial Brain Calcification

About this section
NINDS:46 Fahr's Syndrome is a rare, genetically dominant, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex. Symptoms of the disorder may include deterioration of motor function, dementia, seizures, headache, (poorly articulated speech), (stiffness of the limbs) and spastic paralysis, eye impairments, and (involuntary, writhing movements). Fahr's Syndrome can also include symptoms characteristic of Parkinson's disease such as tremors, muscle rigidity, a mask-like facial appearance, shuffling gait, and a "pill-rolling" motion of the fingers. These symptoms generally occur later in the development of the disease. More common symptoms include dystonia (disordered muscle tone) and chorea (involuntary, rapid, jerky movements). Age of onset is typically in the 40s or 50s, although it can occur at any time in childhood or adolescence.

MalaCards based summary: Primary Familial Brain Calcification, also known as familial idiopathic basal ganglia calcification, is related to basal ganglia calcification, idiopathic, 5 and basal ganglia calcification, and has symptoms including microcephaly, seizures and intrauterine growth retardation. An important gene associated with Primary Familial Brain Calcification is SLC20A2 (Solute Carrier Family 20 (Phosphate Transporter), Member 2), and among its related pathways are Choline metabolism in cancer and Glioblastoma Multiforme. Affiliated tissues include brain, eye and cortex.

Genetics Home Reference:23 Familial idiopathic basal ganglia calcification (FIBGC, formerly known as Fahr disease) is a condition characterized by abnormal deposits of calcium (calcification) in the brain. These calcium deposits typically occur in the basal ganglia, which are structures deep within the brain that help start and control movement; however, other brain regions can also be affected.

NIH Rare Diseases:45 Primary familial brain calcification (pfbc) is a neurodegenerative disorder characterized by calcium deposits in the basal ganglia, a part of the brain that helps start and control movement. the first symptoms often include clumsiness, fatigue, unsteady walking (gait), slow or slurred speech, difficulty swallowing (dysphagia) and dementia. migraines and seizures frequently occur. symptoms typically start in an individual's 30's to 40's but may begin at any age.the neuropsychiatric symptoms and movement disorders worsen over time. mutations in the slc20a2, pdgfrb, and pdgfb genes have been found to cause pfbc. this condition is inherited in an autosomal dominant manner. last updated: 9/4/2015
