Genes affected

PIP4K2B (HGNC:8998): (phosphatidylinositol-5-phosphate 4-kinase type 2 beta) The protein encoded by this gene catalyzes the phosphorylation of phosphatidylinositol-5-phosphate on the fourth hydroxyl of the myo-inositol ring to form phosphatidylinositol-5,4-bisphosphate. This gene is a member of the phosphatidylinositol-5-phosphate 4-kinase family. The encoded protein sequence does not show similarity to other kinases, but the protein does exhibit kinase activity. Additionally, the encoded protein interacts with p55 TNF receptor. [provided by RefSeq, Jul 2008]

The c.928G>C (p.D310H) alteration is located in exon 8 (coding exon 8) of the PIP4K2B gene. This alteration results from a G to C substitution at nucleotide position 928, causing the aspartic acid (D) at amino acid position 310 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
