Genes affected

INPP5A (HGNC:6076): (inositol polyphosphate-5-phosphatase A) The protein encoded by this gene is a membrane-associated type I inositol 1,4,5-trisphosphate (InsP3) 5-phosphatase. InsP3 5-phosphatases hydrolyze Ins(1,4,5)P3, which mobilizes intracellular calcium and acts as a second messenger mediating cell responses to various stimulation. [provided by RefSeq, Jul 2008]

The c.158G>C (p.C53S) alteration is located in exon 3 (coding exon 3) of the INPP5A gene. This alteration results from a G to C substitution at nucleotide position 158, causing the cysteine (C) at amino acid position 53 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
