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. Mutations in this gene have been found in patients with velocardiofacial syndrome. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

A study in human forensic autopsy cases demonstrated that methamphetamine intoxication was associated with lower mRNA expression of the CLDN5 compared to other causes of death, suggesting a mechanism for increased blood-brain barrier permeability [Wang et al. DOI:10.1007/S00414-014-0972-6]. In a mouse model of developmental lead exposure, single-cell RNA sequencing identified the CLDN5 as a marker gene for endothelial cell clusters in the hippocampus [Bakulski et al. DOI:10.1093/toxsci/kfaa069]. A study in human forensic autopsy cases demonstrated that the CLDN5 mRNA expression was significantly higher in fatal hyperthermia compared to other causes of death such as acute cardiac death, mechanical asphyxiation, fire fatality, and intoxication [Wang et al. DOI:10.1016/J.Forsciint.2013.03.007]. Another study in human autopsy cases of injury found that the CLDN5 mRNA expression was significantly higher in subacute deaths due to sharp instrument injury compared to acute cardiac death and other injury groups, though its protein immunostaining showed no significant differences among causes of death [Wang et al. DOI:10.1007/S00414-012-0758-7].
