Genes affected

BEAN1 (HGNC:24160): (brain expressed associated with NEDD4 1) The protein encoded by this gene is one of several proteins that interact with NEDD4, a member of a family of ubiquitin-protein ligases. These proteins have PY motifs in common that bind to the WW domains of NEDD4. NEDD4 is developmentally regulated, and is highly expressed in embryonic tissues. Mutations in this gene (i.e., intronic insertions of >100 copies of pentanucleotide repeats including a (TGGAA)n sequence) are associated with spinocerebellar ataxia type 31. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

The c.331C>T (p.R111C) alteration is located in exon 4 (coding exon 3) of the BEAN1 gene. This alteration results from a C to T substitution at nucleotide position 331, causing the arginine (R) at amino acid position 111 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
