Genes affected

GCC2 (HGNC:23218): (GRIP and coiled-coil domain containing 2) The protein encoded by this gene is a peripheral membrane protein localized to the trans-Golgi network. It is sensitive to brefeldin A. This encoded protein contains a GRIP domain which is thought to be used in targeting. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2009]

The c.995A>G (p.E332G) alteration is located in exon 6 (coding exon 6) of the GCC2 gene. This alteration results from a A to G substitution at nucleotide position 995, causing the glutamic acid (E) at amino acid position 332 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
