Genes affected

SCG5 (HGNC:10816): (secretogranin V) This gene encodes a secreted chaperone protein that prevents the aggregation of other secreted proteins, including proteins that are associated with neurodegenerative and metabolic disease. The encoded protein may be best known for its role in the trafficking and activation of prohormone convertase PC2 (encoded by Gene ID: 5126). Phosphorylation of the encoded protein has been shown to have an inhibitory effect on its chaperone function. This gene also produces a ARHGAP11A-SCG5 readthrough transcript and ARHGAP11A-SCG5 protein. [provided by RefSeq, Feb 2019]

Ambry Genetics

Dec 07, 2021

The c.11G>A (p.R4K) alteration is located in exon 2 (coding exon 1) of the SCG5 gene. This alteration results from a G to A substitution at nucleotide position 11, causing the arginine (R) at amino acid position 4 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
