Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 1P and 8B. PP2BP4_ModerateBP6_ModerateBS1

The NM_005026.5(PIK3CD):c.4C>A(p.Pro2Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000874 in 1,613,946 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P2L) has been classified as Uncertain significance.

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 -7 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=0.12227568).

BP6

Variant 1-9710459-C-A is Benign according to our data. Variant chr1-9710459-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 1138980.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000263 (4/152250) while in subpopulation SAS AF= 0.000622 (3/4826). AF 95% confidence interval is 0.000169. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
