Genes affected

ITPRIP (HGNC:29370): (inositol 1,4,5-trisphosphate receptor interacting protein) This gene encodes a membrane-associated protein that binds the inositol 1,4,5-trisphosphate receptor (ITPR). The encoded protein enhances the sensitivity of ITPR to intracellular calcium signaling. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

Collection Method: clinical testing

The c.1072G>C (p.D358H) alteration is located in exon 3 (coding exon 1) of the ITPRIP gene. This alteration results from a G to C substitution at nucleotide position 1072, causing the aspartic acid (D) at amino acid position 358 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
