Genes affected
CACNA1C (HGNC:1390): (calcium voltage-gated channel subunit alpha1 C) This gene encodes an alpha-1 subunit of a voltage-dependent calcium channel. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization. The alpha-1 subunit consists of 24 transmembrane segments and forms the pore through which ions pass into the cell. The calcium channel consists of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. There are multiple isoforms of each of these proteins, either encoded by different genes or the result of alternative splicing of transcripts. The protein encoded by this gene binds to and is inhibited by dihydropyridine. Alternative splicing results in many transcript variants encoding different proteins. Some of the predicted proteins may not produce functional ion channel subunits. [provided by RefSeq, Oct 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2
Missense variant in the CACNA1C gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 91 curated benign missense variants. Gene score misZ: 6.4654 (above the threshold of 3.09). Trascript score misZ: 7.2674 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual disability, neurodevelopmental disorder with hypotonia, language delay, and skeletal defects with or without seizures, Brugada syndrome, long QT syndrome, short QT syndrome, long qt syndrome 8, Timothy syndrome, Brugada syndrome 3.
BP4
Computational evidence support a benign effect (MetaRNN=0.17819947).
BP6
Variant 12-2115245-G-A is Benign according to our data. Variant chr12-2115245-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 93422.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}.
BS2
High AC in GnomAdExome4 at 22 AD gene.
