Genes affected

CLDN25 (HGNC:37218): (claudin 25) This gene encodes a member of the claudin family. Claudins are integral membrane proteins and components of tight junction strands. Tight junction strands serve as a physical barrier to prevent solutes and water from passing freely through the paracellular space between epithelial or endothelial cell sheets, and also play critical roles in maintaining cell polarity and signal transductions.

Collection Method: clinical testing

The c.614C>G (p.P205R) alteration is located in exon 1 (coding exon 1) of the CLDN25 gene. This alteration results from a C to G substitution at nucleotide position 614, causing the proline (P) at amino acid position 205 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
