Genes affected

TM4SF4 (HGNC:11856): (transmembrane 4 L six family member 4) 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 glycoprotein that can regulate cell proliferation.[provided by RefSeq, Mar 2011]

Ambry Genetics

Dec 15, 2023

The c.34G>A (p.G12R) alteration is located in exon 1 (coding exon 1) of the TM4SF4 gene. This alteration results from a G to A substitution at nucleotide position 34, causing the glycine (G) at amino acid position 12 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
