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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2023The c.247C>T (p.L83F) alteration is located in exon 1 (coding exon 1) of the CLDN25 gene. This alteration results from a C to T substitution at nucleotide position 247, causing the leucine (L) at amino acid position 83 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
