Genes affected
CACNA1D (HGNC:1391): (calcium voltage-gated channel subunit alpha1 D) Voltage-dependent calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, and gene expression. Calcium channels are multisubunit complexes composed of alpha-1, beta, alpha-2/delta, and gamma subunits. The channel activity is directed by the pore-forming alpha-1 subunit, whereas the others act as auxiliary subunits regulating this activity. The distinctive properties of the calcium channel types are related primarily to the expression of a variety of alpha-1 isoforms, namely alpha-1A, B, C, D, E, and S. This gene encodes the alpha-1D subunit. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

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), CACNA1D. . Gene score misZ 4.5817 (greater than the threshold 3.09). Trascript score misZ 6.6047 (greater than threshold 3.09). GenCC has associacion of gene with sinoatrial node dysfunction and deafness, aldosterone-producing adenoma with seizures and neurological abnormalities.
BP4
Computational evidence support a benign effect (MetaRNN=0.17153952).
