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: 6.6073 (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.

BP4

Computational evidence support a benign effect (MetaRNN=0.004864514).

BP6

Variant 3-53811357-G-A is Benign according to our data. Variant chr3-53811357-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 226479.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00129 (197/152314) while in subpopulation AFR AF= 0.00464 (193/41570). AF 95% confidence interval is 0.00411. There are 1 homozygotes in gnomad4. There are 88 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
