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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.355G>A (p.V119I) alteration is located in exon 2 (coding exon 2) of the PI4K2B gene. This alteration results from a G to A substitution at nucleotide position 355, causing the valine (V) at amino acid position 119 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
