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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.164A>C (p.N55T) alteration is located in exon 4 (coding exon 2) of the TSPAN9 gene. This alteration results from a A to C substitution at nucleotide position 164, causing the asparagine (N) at amino acid position 55 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
