Genes affected

ITPR3 (HGNC:6182): (inositol 1,4,5-trisphosphate receptor type 3) This gene encodes a receptor for inositol 1,4,5-trisphosphate, a second messenger that mediates the release of intracellular calcium. The receptor contains a calcium channel at the C-terminus and the ligand-binding site at the N-terminus. Knockout studies in mice suggest that type 2 and type 3 inositol 1,4,5-trisphosphate receptors play a key role in exocrine secretion underlying energy metabolism and growth.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ITPR3. . Gene score misZ 4.5522 (greater than the threshold 3.09). Trascript score misZ 5.2589 (greater than threshold 3.09). GenCC has associacion of gene with Charcot-Marie-Tooth disease, demyelinating, type 1J.

BP4

Computational evidence support a benign effect (MetaRNN=0.15626404).

BS2

High AC in GnomAd4 at 5 AD gene.
