Genes affected

INPP4B (HGNC:6075): (inositol polyphosphate-4-phosphatase type II B) INPP4B encodes the inositol polyphosphate 4-phosphatase type II, one of the enzymes involved in phosphatidylinositol signaling pathways. This enzyme removes the phosphate group at position 4 of the inositol ring from inositol 3,4-bisphosphate. There is limited data to suggest that the human type II enzyme is subject to alternative splicing, as has been established for the type I enzyme. [provided by RefSeq, Jul 2008]

The c.2396A>G (p.Q799R) alteration is located in exon 25 (coding exon 21) of the INPP4B gene. This alteration results from a A to G substitution at nucleotide position 2396, causing the glutamine (Q) at amino acid position 799 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
