Genes affected
PIK3CG (HGNC:8978): (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit gamma) Phosphoinositide 3-kinases (PI3Ks) phosphorylate inositol lipids and are involved in the immune response. The protein encoded by this gene is a class I catalytic subunit of PI3K. Like other class I catalytic subunits (p110-alpha p110-beta, and p110-delta), the encoded protein binds a p85 regulatory subunit to form PI3K. This gene is located in a commonly deleted segment of chromosome 7 previously identified in myeloid leukemias. Several transcript variants encoding the same protein have been found for this gene.

The c.97T>C (p.S33P) alteration is located in exon 2 (coding exon 1) of the PIK3CG gene. This alteration results from a T to C substitution at nucleotide position 97, causing the serine (S) at amino acid position 33 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
