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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2022The c.851C>T (p.T284I) 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 851, causing the threonine (T) at amino acid position 284 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
