Genes affected
CACNA1I (HGNC:1396): (calcium voltage-gated channel subunit alpha1 I) This gene encodes the pore-forming alpha subunit of a voltage gated calcium channel. The encoded protein is a member of a subfamily of calcium channels referred to as is a low voltage-activated, T-type, calcium channel. The channel encoded by this protein is characterized by a slower activation and inactivation compared to other T-type calcium channels. This protein may be involved in calcium signaling in neurons. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 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), CACNA1I. . Gene score misZ 5.0511 (greater than the threshold 3.09). Trascript score misZ 3.2896 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder, neurodevelopmental disorder with speech impairment and with or without seizures.
