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

Verdict is Benign. Variant got -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
• BP6: Variant 3-53811334-C-T is Benign according to our data. Variant chr3-53811334-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 517570.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-1.27 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000262 (38/1452982) while in subpopulation AMR AF= 0.000473 (21/44352). AF 95% confidence interval is 0.000317. There are 0 homozygotes in gnomad4_exome. There are 14 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
