Genes affected

ITPR1 (HGNC:6180): (inositol 1,4,5-trisphosphate receptor type 1) This gene encodes an intracellular receptor for inositol 1,4,5-trisphosphate. Upon stimulation by inositol 1,4,5-trisphosphate, this receptor mediates calcium release from the endoplasmic reticulum. Mutations in this gene cause spinocerebellar ataxia type 15, a disease associated with an heterogeneous group of cerebellar disorders. Multiple transcript variants have been identified for this gene.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ITPR1. . Gene score misZ 5.5951 (greater than the threshold 3.09). Trascript score misZ 6.2026 (greater than threshold 3.09). GenCC has associacion of gene with spinocerebellar ataxia type 15/16, aniridia-cerebellar ataxia-intellectual disability syndrome, spinocerebellar ataxia type 29.

BP4

Computational evidence support a benign effect (MetaRNN=0.25599712).
