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]

The c.132A>T (p.Q44H) alteration is located in exon 1 (coding exon 1) of the TM4SF4 gene. This alteration results from a A to T substitution at nucleotide position 132, causing the glutamine (Q) at amino acid position 44 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
