Genes affected

TPBG (HGNC:12004): (trophoblast glycoprotein) This gene encodes a leucine-rich transmembrane glycoprotein that may be involved in cell adhesion. The encoded protein is an oncofetal antigen that is specific to trophoblast cells. In adults this protein is highly expressed in many tumor cells and is associated with poor clinical outcome in numerous cancers. Alternate splicing in the 5' UTR results in multiple transcript variants that encode the same protein. [provided by RefSeq, Oct 2009]

Ambry Genetics

Sep 07, 2022

The c.107C>T (p.S36F) alteration is located in exon 3 (coding exon 1) of the TPBG gene. This alteration results from a C to T substitution at nucleotide position 107, causing the serine (S) at amino acid position 36 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
