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]

ARHGAP11A-SCG5 (HGNC:56310): (ARHGAP11A-SCG5 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring ARHGAP11A (Rho GTPase activating protein 11A) and SCG5 (secretogranin V) genes on chromosome 15q13.3. The readthrough transcript encodes a fusion protein that shares sequence identity with both the ARHGAP11A and SCG5 gene products. [provided by RefSeq, Feb 2019]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.573 is higher than 0.05.
