Genes affected

CACNA1H (HGNC:1395): (calcium voltage-gated channel subunit alpha1 H) This gene encodes a T-type member of the alpha-1 subunit family, a protein in the voltage-dependent calcium channel complex. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization and consist of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. The alpha-1 subunit has 24 transmembrane segments and forms the pore through which ions pass into the cell. There are multiple isoforms of each of the proteins in the complex, either encoded by different genes or the result of alternative splicing of transcripts. Alternate transcriptional splice variants, encoding different isoforms, have been characterized for the gene described here. Studies suggest certain mutations in this gene lead to childhood absence epilepsy (CAE). [provided by RefSeq, Jul 2008]

The c.3646G>A (p.D1216N) alteration is located in exon 17 (coding exon 16) of the CACNA1H gene. This alteration results from a G to A substitution at nucleotide position 3646, causing the aspartic acid (D) at amino acid position 1216 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The D1216N variant in the CACNA1H gene has not been reported previously as a pathogenic variant,nor as a benign variant, to our knowledge. This variant was not observed in approximately 6500individuals of European and African American ancestry in the NHLBI Exome Sequencing Project,indicating it is not a common benign variant in these populations. The D1216N variant is asemi-conservative amino acid substitution, which may impact secondary protein structure as theseresidues differ in some properties. This substitution occurs at a position that is not conserved. In silicoanalysis is inconsistent in its predictions as to whether or not the variant is damaging to the proteinstructure/function. We interpret D1216N as a variant of uncertain significance. -
