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.3655G>A (p.G1219R) alteration is located in exon 31 (coding exon 29) of the PPIP5K1 gene. This alteration results from a G to A substitution at nucleotide position 3655, causing the glycine (G) at amino acid position 1219 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
