Genes affected
THNSL1 (HGNC:26160): (threonine synthase like 1)
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.491G>A (p.R164H) alteration is located in exon 3 (coding exon 1) of the THNSL1 gene. This alteration results from a G to A substitution at nucleotide position 491, causing the arginine (R) at amino acid position 164 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
