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 Benign. Variant got -15 ACMG points.

PP2
Missense variant in the CACNA1D gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 11 curated pathogenic missense variants (we use a threshold of 10). The gene has 27 curated benign missense variants. Gene score misZ: 4.5817 (above the threshold of 3.09). Trascript score misZ: 6.6047 (above the threshold of 3.09). GenCC associations: The gene is linked to sinoatrial node dysfunction and deafness, aldosterone-producing adenoma with seizures and neurological abnormalities.

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

p.Ala502Thr in exon 11 of CACNA1D: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. A lanine (Ala) at position 502 is not conserved in mammals or evolutionarily dista nt species and 3 species (marmoset, dolphin, and killer whale) carry a threonine (Thr) at this position, supporting that this change may be tolerated. In additi on, the variant has been identified in 0.4% (94/25942) of Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs773409037). -
