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

Nov 30, 2022

The c.470T>C (p.F157S) alteration is located in exon 7 (coding exon 5) of the TSPAN4 gene. This alteration results from a T to C substitution at nucleotide position 470, causing the phenylalanine (F) at amino acid position 157 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
