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 made for transcript

Verdict is Benign. Variant got -15 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PIK3CD. . Gene score misZ 4.2747 (greater than the threshold 3.09). Trascript score misZ 6.3833 (greater than threshold 3.09). GenCC has associacion of gene with immunodeficiency 14b, autosomal recessive, immunodeficiency 14, activated PI3K-delta syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.010897398).

BP6

Variant 1-9715914-T-A is Benign according to our data. Variant chr1-9715914-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 474031.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-9715914-T-A is described in Lovd as [Likely_benign].

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00113 (169/149698) while in subpopulation NFE AF= 0.00151 (102/67332). AF 95% confidence interval is 0.00128. There are 1 homozygotes in gnomad4. There are 83 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
