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 26, 2022The c.142G>A (p.E48K) alteration is located in exon 6 (coding exon 3) of the TJAP1 gene. This alteration results from a G to A substitution at nucleotide position 142, causing the glutamic acid (E) at amino acid position 48 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
