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.

ENSG00000285859 (HGNC:):

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

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.061974496).

Collection Method: clinical testing

The c.520C>G (p.R174G) alteration is located in exon 4 (coding exon 4) of the ENKUR gene. This alteration results from a C to G substitution at nucleotide position 520, causing the arginine (R) at amino acid position 174 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
