Genes affected

RUBCN (HGNC:28991): (rubicon autophagy regulator) The protein encoded by this gene is a negative regulator of autophagy and endocytic trafficking and controls endosome maturation. This protein contains two conserved domains, an N-terminal RUN domain and a C-terminal DUF4206 domain. The RUN domain is involved in Ras-like GTPase signaling, and the DUF4206 domain contains a diacylglycerol (DAG) binding-like motif. Mutation in this gene results in deletion of the DAG binding-like motif and causes a recessive ataxia. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Apr 2014]

The c.2509A>G (p.M837V) alteration is located in exon 19 (coding exon 18) of the RUBCN gene. This alteration results from a A to G substitution at nucleotide position 2509, causing the methionine (M) at amino acid position 837 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
