Genes affected

FAP (HGNC:3590): (fibroblast activation protein alpha) The protein encoded by this gene is a homodimeric integral membrane gelatinase belonging to the serine protease family. It is selectively expressed in reactive stromal fibroblasts of epithelial cancers, granulation tissue of healing wounds, and malignant cells of bone and soft tissue sarcomas. This protein is thought to be involved in the control of fibroblast growth or epithelial-mesenchymal interactions during development, tissue repair, and epithelial carcinogenesis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2014]

The c.1832G>A (p.G611D) alteration is located in exon 21 (coding exon 21) of the FAP gene. This alteration results from a G to A substitution at nucleotide position 1832, causing the glycine (G) at amino acid position 611 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
