Genes affected

TM4SF1 (HGNC:11853): (transmembrane 4 L six family member 1) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface antigen and is highly expressed in different carcinomas. [provided by RefSeq, Jul 2008]

The c.154G>A (p.G52S) alteration is located in exon 1 (coding exon 1) of the TM4SF1 gene. This alteration results from a G to A substitution at nucleotide position 154, causing the glycine (G) at amino acid position 52 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
