Genes affected
GORASP2 (HGNC:17500): (golgi reassembly stacking protein 2) This gene encodes a member of the Golgi reassembly stacking protein family. These proteins may play a role in the stacking of Golgi cisternae and Golgi ribbon formation, as well as Golgi fragmentation during apoptosis or mitosis. The encoded protein also plays a role in the intracellular transport of transforming growth factor alpha and may function as a molecular chaperone. A pseudogene of this gene is located on the short arm of chromosome 2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 29, 2023 | The c.239G>A (p.R80Q) alteration is located in exon 3 (coding exon 3) of the GORASP2 gene. This alteration results from a G to A substitution at nucleotide position 239, causing the arginine (R) at amino acid position 80 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
