Genes affected

ENKUR (HGNC:28388): (enkurin, TRPC channel interacting protein) This gene encodes a protein that interacts with calmodulin and several transient receptor potential canonical cation channel proteins. The encoded protein may function as an adaptor to localize signal transduction machinery to calcium channels. Alternative splicing results in multiple transcript variants.

Collection Method: clinical testing

The c.718G>A (p.D240N) alteration is located in exon 5 (coding exon 5) of the ENKUR gene. This alteration results from a G to A substitution at nucleotide position 718, causing the aspartic acid (D) at amino acid position 240 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
