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]

The c.788A>T (p.H263L) alteration is located in exon 11 (coding exon 8) of the TJAP1 gene. This alteration results from a A to T substitution at nucleotide position 788, causing the histidine (H) at amino acid position 263 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
