Genes affected

GGA2 (HGNC:16064): (golgi associated, gamma adaptin ear containing, ARF binding protein 2) 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. This family member may play a significant role in cargo molecules regulation and clathrin-coated vesicle assembly. [provided by RefSeq, Jul 2008]

The c.1805A>C (p.K602T) alteration is located in exon 17 (coding exon 17) of the GGA2 gene. This alteration results from a A to C substitution at nucleotide position 1805, causing the lysine (K) at amino acid position 602 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
