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.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.385A>C (p.I129L) alteration is located in exon 3 (coding exon 1) of the THNSL1 gene. This alteration results from a A to C substitution at nucleotide position 385, causing the isoleucine (I) at amino acid position 129 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
