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.829G>A (p.V277I) alteration is located in exon 11 (coding exon 11) of the INPP5A gene. This alteration results from a G to A substitution at nucleotide position 829, causing the valine (V) at amino acid position 277 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
