Genes affected

PPIP5K2 (HGNC:29035): (diphosphoinositol pentakisphosphate kinase 2) This gene encodes a member of the histidine acid phosphatase family of proteins. Despite containing a histidine acid phosphatase domain, the encoded protein functions as an inositol pyrophosphate kinase, and is thought to lack phosphatase activity. This kinase activity is the mechanism by which the encoded protein synthesizes high-energy inositol pyrophosphates, which act as signaling molecules that regulate cellular homeostasis and other processes. This gene may be associated with autism spectrum disorder in human patients. [provided by RefSeq, Sep 2016]

Dec 01, 2022

The c.214T>C (p.Y72H) alteration is located in exon 2 (coding exon 2) of the PPIP5K2 gene. This alteration results from a T to C substitution at nucleotide position 214, causing the tyrosine (Y) at amino acid position 72 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
