Summaries for Chorea, Hereditary Benign

About this section
NIH Rare Diseases:47 Benign hereditary chorea (BHC) is a rare movement disorder that begins in infancy or childhood. Signs and symptoms in infants may include low muscle tone, involuntary movements (chorea), lung infections, and respiratory distress. Signs and symptoms in children may include delayed motor and walking milestones, jerky muscle movements (myoclonus), upper limb dystonia, motor tics, and vocal tics. The chorea often improves with time. In some cases, myoclonus persists or worsens. Children with BHC can have normal intellect, but may have learning and behavior problems. Other signs and symptoms include thyroid problems (e.g., hypothyroidism) and lung disease (e.g., recurring infections). Treatment is tailored to each child. Tetrabenazine and levodopa have been tried in individual cases with some success. BHC is caused by mutations in the NKX2-1 gene (also known as the TITF1 gene). It is passed through families in an autosomal dominant fashion. Last updated: 8/7/2014

MalaCards based summary: Chorea, Hereditary Benign, also known as benign hereditary chorea, is related to choreoathetosis, hypothyroidism, and neonatal respiratory distress and sydenham chorea, and has symptoms including gait disturbance, anxiety and dysarthria. An important gene associated with Chorea, Hereditary Benign is NKX2-1 (NK2 Homeobox 1). Affiliated tissues include thyroid and lung, and related mouse phenotype behavior/neurological.

UniProtKB/Swiss-Prot:69 Chorea, hereditary benign: A rare autosomal dominant movement disorder, defined by early onset in childhood, a stable or non-progressive course of chorea, and no mental deterioration. Chorea is characterized by involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement.
