Genes affected

INPP4A (HGNC:6074): (inositol polyphosphate-4-phosphatase type I A) This gene encodes an Mg++ independent enzyme that hydrolyzes the 4-position phosphate from the inositol ring of phosphatidylinositol 3,4-bisphosphate, inositol 1,3,4-trisphosphate, and inositol 3,4-bisphosphate. Multiple transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Aug 2008]

The c.679G>A (p.G227S) alteration is located in exon 10 (coding exon 8) of the INPP4A gene. This alteration results from a G to A substitution at nucleotide position 679, causing the glycine (G) at amino acid position 227 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
