Genes affected

GORASP1 (HGNC:16769): (golgi reassembly stacking protein 1) The Golgi complex plays a key role in the sorting and modification of proteins exported from the endoplasmic reticulum. The protein encoded by this gene is a membrane protein involved in establishing the stacked structure of the Golgi apparatus. It is a caspase-3 substrate, and cleavage of this encoded protein contributes to Golgi fragmentation in apoptosis. This encoded protein can form a complex with the Golgi matrix protein GOLGA2, and this complex binds to the vesicle docking protein p115. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

Collection Method: clinical testing

The c.928G>A (p.V310M) alteration is located in exon 8 (coding exon 8) of the GORASP1 gene. This alteration results from a G to A substitution at nucleotide position 928, causing the valine (V) at amino acid position 310 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
