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]

Ambry Genetics

Aug 13, 2021

The c.88C>A (p.L30I) alteration is located in exon 3 (coding exon 3) of the GCC2 gene. This alteration results from a C to A substitution at nucleotide position 88, causing the leucine (L) at amino acid position 30 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
