Genes affected
TRO (HGNC:12326): (trophinin) This gene encodes a membrane protein that mediates cell adhesion between trophoblastic cells and the epithelial cells of the endometrium. The encoded protein participates in cell signalling during embryo implantation, and may also be involved in cancer formation. This gene is located near several other closely related genes on chromosome X. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.1346A>G (p.N449S) alteration is located in exon 5 (coding exon 4) of the TRO gene. This alteration results from a A to G substitution at nucleotide position 1346, causing the asparagine (N) at amino acid position 449 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
