Genes affected

PI4K2A (HGNC:30031): (phosphatidylinositol 4-kinase type 2 alpha) Phosphatidylinositolpolyphosphates (PtdInsPs) are centrally involved in many biologic processes, ranging from cell growth and organization of the actin cytoskeleton to endo- and exocytosis. PI4KII phosphorylates PtdIns at the D-4 position, an essential step in the biosynthesis of PtdInsPs (Barylko et al., 2001 [PubMed 11244087]).[supplied by OMIM, Mar 2008]

The c.964A>G (p.M322V) alteration is located in exon 5 (coding exon 5) of the PI4K2A gene. This alteration results from a A to G substitution at nucleotide position 964, causing the methionine (M) at amino acid position 322 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
