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]

May 18, 2023

The c.314A>C (p.Q105P) alteration is located in exon 3 (coding exon 2) of the TRO gene. This alteration results from a A to C substitution at nucleotide position 314, causing the glutamine (Q) at amino acid position 105 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
