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 Likely_benign. Variant got -1 ACMG points.

BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000231 (35/151204) while in subpopulation AFR AF= 0.000486 (20/41140). AF 95% confidence interval is 0.000322. There are 0 homozygotes in gnomad4. There are 21 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
