Genes affected

TSPAN8 (HGNC:11855): (tetraspanin 8) 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 is known to complex with integrins. This gene is expressed in different carcinomas. The use of alternate polyadenylation sites has been found for this gene. [provided by RefSeq, Jul 2008]

Jun 29, 2023

The c.608C>A (p.A203E) alteration is located in exon 8 (coding exon 7) of the TSPAN8 gene. This alteration results from a C to A substitution at nucleotide position 608, causing the alanine (A) at amino acid position 203 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
