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]

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 2117 of the CACNA1D protein (p.Asp2117Asn). This variant is present in population databases (rs41276455, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CACNA1D-related conditions. ClinVar contains an entry for this variant (Variation ID: 504751). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -

The p.Asp2117Asn variant in CACNA1D has not been previously reported in individu als with hearing loss, but has been identified in 4/111704 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org/; d bSNP rs41276455). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational p rediction tools and conservation analyses do not provide strong support for or a gainst an impact to the protein. In summary, the clinical significance of the p. Asp2117Asn variant is uncertain. -
