Genes affected

TSPAN4 (HGNC:11859): (tetraspanin 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 and is similar in sequence to its family member CD53 antigen. It is known to complex with integrins and other transmembrane 4 superfamily proteins. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 14, 2023

The c.644T>C (p.V215A) alteration is located in exon 8 (coding exon 6) of the TSPAN4 gene. This alteration results from a T to C substitution at nucleotide position 644, causing the valine (V) at amino acid position 215 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
