Genes affected

STAU2 (HGNC:11371): (staufen double-stranded RNA binding protein 2) Staufen homolog 2 is a member of the family of double-stranded RNA (dsRNA)-binding proteins involved in the transport and/or localization of mRNAs to different subcellular compartments and/or organelles. These proteins are characterized by the presence of multiple dsRNA-binding domains which are required to bind RNAs having double-stranded secondary structures. Staufen homolog 2 shares 48.5% and 59.9% similarity with drosophila and human staufen, respectively. The exact function of Staufen homolog 2 is not known, but since it contains 3 copies of conserved dsRNA binding domain, it could be involved in double-stranded RNA binding events. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2009]

Ambry Genetics

Nov 14, 2023

The c.1457C>G (p.S486C) alteration is located in exon 13 (coding exon 10) of the STAU2 gene. This alteration results from a C to G substitution at nucleotide position 1457, causing the serine (S) at amino acid position 486 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
