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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 16, 2021 | The c.3877C>T (p.H1293Y) alteration is located in exon 31 (coding exon 29) of the PPIP5K1 gene. This alteration results from a C to T substitution at nucleotide position 3877, causing the histidine (H) at amino acid position 1293 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
