Genes affected
PIK3CD (HGNC:8977): (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta) Phosphoinositide 3-kinases (PI3Ks) phosphorylate inositol lipids and are involved in the immune response. The protein encoded by this gene is a class I PI3K found primarily in leukocytes. Like other class I PI3Ks (p110-alpha p110-beta, and p110-gamma), the encoded protein binds p85 adapter proteins and GTP-bound RAS. However, unlike the other class I PI3Ks, this protein phosphorylates itself, not p85 protein.[provided by RefSeq, Jul 2010]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 3 of the PIK3CD protein (p.Pro3Leu). This variant is present in population databases (rs780051553, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PIK3CD-related conditions. ClinVar contains an entry for this variant (Variation ID: 1384937). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
