Genes affected

TJAP1 (HGNC:17949): (tight junction associated protein 1) This gene encodes a tight junction-associated protein. Incorporation of the encoded protein into tight junctions occurs at a late stage of formation of the junctions. The encoded protein localizes to the Golgi and may function in vesicle trafficking. Alternatively spliced transcript variants have been described. A related pseudogene exists on the X chromosome. [provided by RefSeq, Mar 2009]

Ambry Genetics

Apr 22, 2024

The c.956C>T (p.P319L) alteration is located in exon 11 (coding exon 8) of the TJAP1 gene. This alteration results from a C to T substitution at nucleotide position 956, causing the proline (P) at amino acid position 319 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
