Summaries for Behr Syndrome

OMIM® : 57 'Behr syndrome' is a clinical term that refers to the constellation of early-onset optic atrophy accompanied by neurologic features, including ataxia, pyramidal signs, spasticity, and mental retardation (Behr, 1909; Thomas et al., 1984). Patients with mutations in genes other than OPA1 can present with clinical features reminiscent of Behr syndrome. Mutations in one of these genes, OPA3 (606580), result in type III 3-methylglutaconic aciduria (MGCA3; 258501). Lerman-Sagie (1995) noted that the abnormal urinary pattern in MGCA3 may not be picked up by routine organic acid analysis, suggesting that early reports of Behr syndrome with normal metabolic features may actually have been 3-methylglutaconic aciduria type III. (210000) (Updated 20-May-2021)

MalaCards based summary : Behr Syndrome, also known as abortive cerebellar ataxia, is related to optic atrophy with or without deafness, ophthalmoplegia, myopathy, ataxia, and neuropathy and 3-methylglutaconic aciduria, type iii, and has symptoms including ataxia, tremor and spasm. An important gene associated with Behr Syndrome is OPA1 (OPA1 Mitochondrial Dynamin Like GTPase). The drugs Simvastatin and Atorvastatin have been mentioned in the context of this disorder. Affiliated tissues include heart, brain and eye, and related phenotypes are intellectual disability and hyperreflexia

Disease Ontology : 12 A nervous system disease characterized by early-onset optic atrophy, ataxia, pyramidal signs, spasticity, and intellectual disability that has material basis in homozygous or compound heterozygous mutation in OPA1 on chromosome 3q29.

GARD : 20 Behr syndrome is a disorder characterized by early-onset optic atrophy along with neurological features, including ataxia, spasticity, and intellectual disability. Other signs and symptoms may be present and vary from person to person. This condition is caused by mutations in the OPA1 gene. It is inherited in an autosomal recessive manner. Treatment depends on the specific signs and symptoms seen in the patient.

UniProtKB/Swiss-Prot : 72 Behr syndrome: An autosomal recessive syndrome characterized by optic atrophy beginning in early childhood associated with ataxia, pyramidal signs, spasticity, mental retardation, and posterior column sensory loss. The ataxia, spasticity, and muscle contractures, mainly of the hip adductors, hamstrings, and soleus, are progressive and become more prominent in the second decade.
