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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Mar 08, 2022	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1305302). This variant has not been reported in the literature in individuals affected with CACNA1D-related conditions. This variant is present in population databases (rs760088044, gnomAD 0.007%). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 16 of the CACNA1D protein (p.Gln16Arg). -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 25, 2019	Has not been previously published as pathogenic or benign to our knowledge -
