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]

Collection Method:clinical testing

The c.82T>A (p.S28T) alteration is located in exon 2 (coding exon 2) of the TGFA gene. This alteration results from a T to A substitution at nucleotide position 82, causing the serine (S) at amino acid position 28 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
