Genes affected

SIRPG (HGNC:15757): (signal regulatory protein gamma) The protein encoded by this gene is a member of the signal-regulatory protein (SIRP) family, and also belongs to the immunoglobulin superfamily. SIRP family members are receptor-type transmembrane glycoproteins known to be involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

SIRPB3P (HGNC:49209): (signal regulatory protein beta 3, pseudogene)

ENSG00000296776 (HGNC:):

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.569 is higher than 0.05.
