Hereditary ataxia with onset in adulthood v8.5 RAB3A Sarah Leigh changed review comment from: Hengel et al (PMID: 40166812) report six heterozygous RAB3A variants which appear to be associated with a condition that includes cerebellar ataxia; pyramidal features; neurodevelopmental delay. Five of the variants were only seen in one family each, while (NM_002866.5) c.247C>T (p.Arg83Trp) was seen in 14 members from nine families. The age of onset of phenotypic features ranged from 3 months to adulthood. The authors also present supportive functional studies.; to: Hengel et al (PMID: 40166812) report six heterozygous RAB3A variants which appear to be associated with a condition that includes cerebellar ataxia; pyramidal features; neurodevelopmental delay.

The age of onset of phenotypic features ranged from 3 months to adulthood. This gene is appropriate for the Hereditary ataxia with onset in adulthood panel as PMID: 40166812 states "The median age at onset was 26.5 (interquartile range (IQR) 22–32) with gait ataxia as the first symptom in all probands.", In addition, the authors also present supportive functional studies.
