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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.363C>G (p.I121M) alteration is located in exon 1 (coding exon 1) of the PI4K2A gene. This alteration results from a C to G substitution at nucleotide position 363, causing the isoleucine (I) at amino acid position 121 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
