Autosomal recessive spinocerebellar ataxia 13
MONDO:0013905Autosomal recessive congenital cerebellar ataxia due to MGLUR1 deficiency is a rare, genetic, slowly progressive neurodegenerative disease resulting from MGLUR1 deficiency characterized by global developmental delay (beginning in infancy), mild to severe intellectual deficit with poor or absent speech, moderate to severe stance and gait ataxia, pyramidal signs (e.g. hyperreflexia) and mild dysdiadochokinesia, dysmetria, tremors, and/or dysarthria. Oculomotor signs, such as nystagmus, strabismus, ptosis and hypometric saccades, may also be associated. Brain imaging reveals progressive, generalized, moderate to severe cerebellar atrophy, inferior vermian hypoplasia, and/or constitutionally small brain.
Also known as: GRM1 autosomal recessive cerebellar ataxia - pyramidal signs - nystagmus - oculomotor apraxia syndrome, GRM1 autosomal recessive cerebellar ataxia-pyramidal signs-nystagmus-oculomotor apraxia syndrome, SCAR13, autosomal recessive cerebellar ataxia - pyramidal signs - nystagmus - oculomotor apraxia syndrome caused by mutation in GRM1, autosomal recessive cerebellar ataxia-pyramidal signs-nystagmus-oculomotor apraxia syndrome caused by mutation in GRM1, autosomal recessive congenital cerebellar ataxia due to metabotropic glutamate receptor 1 deficiency, autosomal recessive spinocerebellar ataxia 13, autosomal recessive spinocerebellar ataxia type 13

Can intense walking training help brain injury patients walk better?
Symptom relief Not yet recruitingThis study looks at whether high-intensity walking training can help people with cerebellar damage (a part of the brain that controls balance and coordination) improve their walking ability. Twenty participants will either do intense walking exercises or standard training. The go…

AI vs. experts: can a computer judge speech as well as a human?
Knowledge-focused Not yet recruitingThis study will compare how well an AI program (Blings) measures speech clarity in 40 adults with speech disorders from stroke or other neurological conditions. Two speech therapists will also rate the same speech samples. The goal is to see if the AI can reliably replace or assi…
