Genes affected

GGA1 (HGNC:17842): (golgi associated, gamma adaptin ear containing, ARF binding protein 1) This gene encodes a member of the Golgi-localized, gamma adaptin ear-containing, ARF-binding (GGA) protein family. Members of this family are 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 encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Sep 10, 2024

The c.40A>G (p.I14V) alteration is located in exon 1 (coding exon 1) of the GGA1 gene. This alteration results from a A to G substitution at nucleotide position 40, causing the isoleucine (I) at amino acid position 14 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
