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.77C>T (p.A26V) alteration is located in exon 3 (coding exon 1) of the INPP4A gene. This alteration results from a C to T substitution at nucleotide position 77, causing the alanine (A) at amino acid position 26 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
