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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0024999976).
BP6
Variant 1-9717541-C-G is Benign according to our data. Variant chr1-9717541-C-G is described in ClinVar as Benign. ClinVar VariationId is 440066.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0187 (2851/152378) while in subpopulation NFE AF = 0.027 (1834/68042). AF 95% confidence interval is 0.0259. There are 45 homozygotes in GnomAd4. There are 1338 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 45 AD,AR,Unknown gene
