THNSL1 links:

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.

Ambry Genetics

Feb 21, 2024

The c.74C>T (p.T25M) alteration is located in exon 3 (coding exon 1) of the THNSL1 gene. This alteration results from a C to T substitution at nucleotide position 74, causing the threonine (T) at amino acid position 25 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
