Genes affected
TGFA (HGNC:11765): (transforming growth factor alpha) This gene encodes a growth factor that is a ligand for the epidermal growth factor receptor, which activates a signaling pathway for cell proliferation, differentiation and development. This protein may act as either a transmembrane-bound ligand or a soluble ligand. This gene has been associated with many types of cancers, and it may also be involved in some cases of cleft lip/palate. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 03, 2024 | The c.99C>G (p.D33E) alteration is located in exon 3 (coding exon 3) of the TGFA gene. This alteration results from a C to G substitution at nucleotide position 99, causing the aspartic acid (D) at amino acid position 33 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
