Genes affected

EXOC5 (HGNC:10696): (exocyst complex component 5) The protein encoded by this gene is a component of the exocyst complex, a multiple protein complex essential for targeting exocytic vesicles to specific docking sites on the plasma membrane. Though best characterized in yeast, the component proteins and functions of exocyst complex have been demonstrated to be highly conserved in higher eukaryotes. At least eight components of the exocyst complex, including this protein, are found to interact with the actin cytoskeletal remodeling and vesicle transport machinery. The complex is also essential for the biogenesis of epithelial cell surface polarity. [provided by RefSeq, Jul 2008]

The c.1978C>G (p.L660V) alteration is located in exon 18 (coding exon 18) of the EXOC5 gene. This alteration results from a C to G substitution at nucleotide position 1978, causing the leucine (L) at amino acid position 660 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
