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]

Ambry Genetics

Dec 17, 2023

The c.1576G>A (p.A526T) alteration is located in exon 19 (coding exon 15) of the INPP4B gene. This alteration results from a G to A substitution at nucleotide position 1576, causing the alanine (A) at amino acid position 526 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
