Genes affected

THNSL1 (HGNC:26160): (threonine synthase like 1)

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.

The c.23A>G (p.H8R) alteration is located in exon 3 (coding exon 1) of the THNSL1 gene. This alteration results from a A to G substitution at nucleotide position 23, causing the histidine (H) at amino acid position 8 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
