Genes affected

GGA3 (HGNC:17079): (golgi associated, gamma adaptin ear containing, ARF binding protein 3) This gene encodes a member of the Golgi-localized, gamma adaptin ear-containing, ARF-binding (GGA) family. This family includes ubiquitous coat proteins that regulate the trafficking of proteins between the trans-Golgi network and the lysosome. These proteins share an amino-terminal VHS domain which mediates sorting of the mannose 6-phosphate receptors at the trans-Golgi network. They also contain a carboxy-terminal region with homology to the ear domain of gamma-adaptins. Multiple alternatively spliced transcript variants have been identified in this gene.

The c.1579A>G (p.K527E) alteration is located in exon 13 (coding exon 13) of the GGA3 gene. This alteration results from a A to G substitution at nucleotide position 1579, causing the lysine (K) at amino acid position 527 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
