Genes affected

GOLGA1 (HGNC:4424): (golgin A1) The Golgi apparatus, which participates in glycosylation and transport of proteins and lipids in the secretory pathway, consists of a series of stacked cisternae (flattened membrane sacs). Interactions between the Golgi and microtubules are thought to be important for the reorganization of the Golgi after it fragments during mitosis. This gene encodes one of the golgins, a family of proteins localized to the Golgi. This encoded protein is associated with Sjogren's syndrome. [provided by RefSeq, Feb 2010]

The c.2237G>C (p.G746A) alteration is located in exon 23 (coding exon 21) of the GOLGA1 gene. This alteration results from a G to C substitution at nucleotide position 2237, causing the glycine (G) at amino acid position 746 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
