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 was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP3

Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

BP6

Variant 3-53730470-C-A is Benign according to our data. Variant chr3-53730470-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 417905.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000348 (53/152306) while in subpopulation NFE AF = 0.000603 (41/68030). AF 95% confidence interval is 0.000457. There are 0 homozygotes in GnomAd4. There are 24 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
