Genes affected
CLDN5 (HGNC:2047): (claudin 5) 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.

The c.848T>G (p.V283G) alteration is located in exon 1 (coding exon 1) of the CLDN5 gene. This alteration results from a T to G substitution at nucleotide position 848, causing the valine (V) at amino acid position 283 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
