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

AI boosts brain scan accuracy in massive new trial
Diagnosis ENROLLING_BY_INVITATIONThis study tests whether an AI tool can help radiologists read brain CT and MRI scans more accurately and quickly. Researchers will compare how well doctors, AI alone, and doctors using AI together can spot abnormalities, urgent findings, and classify diseases. The goal is to red…

New vitamin supplements aim to make life easier for kids with rare metabolic disorders
Symptom relief OngoingThis study tests new vitamin and mineral supplements called EasiVits for children aged 1-16 with inborn errors of metabolism (IEM). These supplements have less carbohydrate and no flavor, so they can be used with different diets and kids can add their own taste. The goal is to se…

Can a gentle brain zap help people with ataxia walk better?
Symptom relief OngoingThis study tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can improve movement in people with degenerative ataxia, a rare condition that damages the cerebellum and impairs balance and coordination. Sixteen participan…
