Genes affected

PIK3AP1 (HGNC:30034): (phosphoinositide-3-kinase adaptor protein 1) Predicted to enable phosphatidylinositol 3-kinase regulatory subunit binding activity and signaling receptor binding activity. Predicted to be involved in regulation of inflammatory response; regulation of signal transduction; and toll-like receptor signaling pathway. Predicted to be located in cytoplasm and membrane. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.006027162).
• BP6: Variant 10-96626726-C-T is Benign according to our data. Variant chr10-96626726-C-T is described in ClinVar as [Benign]. Clinvar id is 474917.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00112 (170/152324) while in subpopulation EAS AF= 0.0237 (123/5180). AF 95% confidence interval is 0.0203. There are 2 homozygotes in gnomad4. There are 105 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 170 AD gene.
