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]

Likely benign, criteria provided, single submitter	clinical testing	Genetic Services Laboratory, University of Chicago	Jul 07, 2020	- -
Likely benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jun 13, 2017	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). -
Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Jan 04, 2018	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. -
