Genes affected
CLDN4 (HGNC:2046): (claudin 4) The protein encoded by this intronless gene belongs to the claudin family. Claudins are integral membrane proteins that are components of the epithelial cell tight junctions, which regulate movement of solutes and ions through the paracellular space. This protein is a high-affinity receptor for Clostridium perfringens enterotoxin (CPE) and may play a role in internal organ development and function during pre- and postnatal life. This gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. [provided by RefSeq, Sep 2013]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.560C>A (p.P187H) alteration is located in exon 1 (coding exon 1) of the CLDN4 gene. This alteration results from a C to A substitution at nucleotide position 560, causing the proline (P) at amino acid position 187 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
