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]

Ambry Genetics

Feb 15, 2023

The c.893C>T (p.S298L) alteration is located in exon 4 (coding exon 4) of the SIRPG gene. This alteration results from a C to T substitution at nucleotide position 893, causing the serine (S) at amino acid position 298 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
