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]

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. -
