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 GeneticsSep 17, 2021The c.115C>G (p.R39G) alteration is located in exon 1 (coding exon 1) of the PI4K2B gene. This alteration results from a C to G substitution at nucleotide position 115, causing the arginine (R) at amino acid position 39 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
