Definitions related to behr syndrome:
-
An autosomal recessive condition caused by mutation(s) in the OPA1 gene, encoding dynamin-like 120 kDa protein, mitochondrial. It is characterized by optic atrophy and neurological features, which may include ophthalmoparesis, nystagmus, spastic paraparesis, ataxia, peripheral neuropathy and learning difficulties.NCI ThesaurusU.S. National Cancer Institute, 2021

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.

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...National Center for Advancing Translational Sciences
