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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.1807G>A (p.D603N) alteration is located in exon 15 (coding exon 15) of the GGA3 gene. This alteration results from a G to A substitution at nucleotide position 1807, causing the aspartic acid (D) at amino acid position 603 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
