Genes affected

CLDN10 (HGNC:2033): (claudin 10) 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. The expression level of this gene is associated with recurrence of primary hepatocellular carcinoma. Six alternatively spliced transcript variants encoding different isoforms have been reported, but the transcript sequences of some variants are not determined.[provided by RefSeq, Jun 2010]

Jan 04, 2024

The c.127G>T (p.A43S) alteration is located in exon 1 (coding exon 1) of the CLDN10 gene. This alteration results from a G to T substitution at nucleotide position 127, causing the alanine (A) at amino acid position 43 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
