Genes affected

EXOC7 (HGNC:23214): (exocyst complex component 7) The protein encoded by this gene is a component of the exocyst complex. The exocyst complex plays a critical role in vesicular trafficking and the secretory pathway by targeting post-Golgi vesicles to the plasma membrane. The encoded protein is required for assembly of the exocyst complex and docking of the complex to the plasma membrane. The encoded protein may also play a role in pre-mRNA splicing through interactions with pre-mRNA-processing factor 19. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 4.

The c.1820C>A (p.S607Y) alteration is located in exon 16 (coding exon 16) of the EXOC7 gene. This alteration results from a C to A substitution at nucleotide position 1820, causing the serine (S) at amino acid position 607 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
