Genes affected

GOLGA8A (HGNC:31972): (golgin A8 family member A) The Golgi apparatus, which participates in glycosylation and transport of proteins and lipids in the secretory pathway, consists of a series of stacked, flattened membrane sacs referred to as cisternae. Interactions between the Golgi and microtubules are thought to be important for the reorganization of the Golgi after it fragments during mitosis. The golgins constitute a family of proteins which are localized to the Golgi. This gene encodes a golgin which structurally resembles its family member GOLGA2, suggesting that they may share a similar function. There are many similar copies of this gene on chromosome 15. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2009]

May 04, 2023

The c.1558A>G (p.S520G) alteration is located in exon 15 (coding exon 15) of the GOLGA8A gene. This alteration results from a A to G substitution at nucleotide position 1558, causing the serine (S) at amino acid position 520 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
