Genes affected

INPP1 (HGNC:6071): (inositol polyphosphate-1-phosphatase) This gene encodes the enzyme inositol polyphosphate-1-phosphatase, one of the enzymes involved in phosphatidylinositol signaling pathways. This enzyme removes the phosphate group at position 1 of the inositol ring from the polyphosphates inositol 1,4-bisphosphate and inositol 1,3,4-trisphophosphate. [provided by RefSeq, Jul 2008]

The c.245A>G (p.N82S) alteration is located in exon 4 (coding exon 2) of the INPP1 gene. This alteration results from a A to G substitution at nucleotide position 245, causing the asparagine (N) at amino acid position 82 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
