Genes affected

PIP4K2A (HGNC:8997): (phosphatidylinositol-5-phosphate 4-kinase type 2 alpha) Phosphatidylinositol-5,4-bisphosphate, the precursor to second messengers of the phosphoinositide signal transduction pathways, is thought to be involved in the regulation of secretion, cell proliferation, differentiation, and motility. The protein encoded by this gene is one of a family of enzymes capable of catalyzing the phosphorylation of phosphatidylinositol-5-phosphate on the fourth hydroxyl of the myo-inositol ring to form phosphatidylinositol-5,4-bisphosphate. The amino acid sequence of this enzyme does not show homology to other kinases, but the recombinant protein does exhibit kinase activity. This gene is a member of the phosphatidylinositol-5-phosphate 4-kinase family. [provided by RefSeq, Jul 2008]

The c.361C>T (p.P121S) alteration is located in exon 4 (coding exon 4) of the PIP4K2A gene. This alteration results from a C to T substitution at nucleotide position 361, causing the proline (P) at amino acid position 121 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
