Genes affected

PI4K2B (HGNC:18215): (phosphatidylinositol 4-kinase type 2 beta) This gene encodes a member of the type II PI4 kinase protein family. The encoded protein is primarily cytosolic and contributes to overall PI4-kinase activity along with other protein family members. This protein is involved in early T cell activation.

SEPSECS-AS1 (HGNC:27737): (SEPSECS antisense RNA 1 (head to head))

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.169 is higher than 0.05.
