Genes affected

PPIP5K1 (HGNC:29023): (diphosphoinositol pentakisphosphate kinase 1) This gene encodes a dual functional inositol kinase. The encoded enzyme converts inositol hexakisphosphate to diphosphoinositol pentakisphosphate and diphosphoinositol pentakisphosphate to bis-diphosphoinositol tetrakisphosphate. This protein may be important for intracellular signaling pathways. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 15.[provided by RefSeq, Jun 2010]

The c.3978G>T (p.Q1326H) alteration is located in exon 31 (coding exon 29) of the PPIP5K1 gene. This alteration results from a G to T substitution at nucleotide position 3978, causing the glutamine (Q) at amino acid position 1326 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
