Genes affected

TSPAN9 (HGNC:21640): (tetraspanin 9) 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. Alternatively spliced transcripts encoding the same protein have been identified. [provided by RefSeq, Nov 2009]

Dec 04, 2024

The c.620C>T (p.T207M) alteration is located in exon 8 (coding exon 6) of the TSPAN9 gene. This alteration results from a C to T substitution at nucleotide position 620, causing the threonine (T) at amino acid position 207 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
