Genes affected

CLDN15 (HGNC:2036): (claudin 15) 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. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jun 2010]

Collection Method: clinical testing

The c.259C>A (p.L87I) alteration is located in exon 3 (coding exon 2) of the CLDN15 gene. This alteration results from a C to A substitution at nucleotide position 259, causing the leucine (L) at amino acid position 87 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
