Genes affected

TGOLN2 (HGNC:15450): (trans-golgi network protein 2) This gene encodes a type I integral membrane protein that is localized to the trans-Golgi network, a major sorting station for secretory and membrane proteins. The encoded protein cycles between early endosomes and the trans-Golgi network, and may play a role in exocytic vesicle formation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2011]

The c.589G>A (p.G197S) alteration is located in exon 2 (coding exon 2) of the TGOLN2 gene. This alteration results from a G to A substitution at nucleotide position 589, causing the glycine (G) at amino acid position 197 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
