Genes affected

IP6K3 (HGNC:17269): (inositol hexakisphosphate kinase 3) This gene encodes a protein that belongs to the inositol phosphokinase (IPK) family. This protein is likely responsible for the conversion of inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). It may also convert 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4. Alternative splicing results in multiple transcript variants encoding the same protein.[provided by RefSeq, Dec 2008]

The c.697G>C (p.A233P) alteration is located in exon 6 (coding exon 4) of the IP6K3 gene. This alteration results from a G to C substitution at nucleotide position 697, causing the alanine (A) at amino acid position 233 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
