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]

Ambry Genetics

Feb 01, 2023

The c.661G>A (p.A221T) alteration is located in exon 9 (coding exon 7) of the TSPAN9 gene. This alteration results from a G to A substitution at nucleotide position 661, causing the alanine (A) at amino acid position 221 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
