Genes affected

CLDN7 (HGNC:2049): (claudin 7) 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. Differential expression of this gene has been observed in different types of malignancies, including breast cancer, ovarian cancer, hepatocellular carcinomas, urinary tumors, prostate cancer, lung cancer, head and neck cancers, thyroid carcinomas, etc.. Alternatively spliced transcript variants encoding different isoforms have been found.[provided by RefSeq, May 2010]

Ambry Genetics

Jun 25, 2024

The c.8A>G (p.N3S) alteration is located in exon 1 (coding exon 1) of the CLDN7 gene. This alteration results from a A to G substitution at nucleotide position 8, causing the asparagine (N) at amino acid position 3 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
