Genes affected

PATJ (HGNC:28881): (PATJ crumbs cell polarity complex component) This gene encodes a protein with multiple PDZ domains. PDZ domains mediate protein-protein interactions, and proteins with multiple PDZ domains often organize multimeric complexes at the plasma membrane. This protein localizes to tight junctions and to the apical membrane of epithelial cells. A similar protein in Drosophila is a scaffolding protein which tethers several members of a multimeric signaling complex in photoreceptors. [provided by RefSeq, Jul 2008]

The c.1909C>T (p.R637W) alteration is located in exon 16 (coding exon 15) of the PATJ gene. This alteration results from a C to T substitution at nucleotide position 1909, causing the arginine (R) at amino acid position 637 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
