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]

Ambry Genetics

Jul 06, 2021

The c.11C>T (p.S4L) alteration is located in exon 1 (coding exon 1) of the TGFA gene. This alteration results from a C to T substitution at nucleotide position 11, causing the serine (S) at amino acid position 4 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
