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 GeneticsMar 18, 2024The c.343G>A (p.A115T) alteration is located in exon 6 (coding exon 4) of the TSPAN9 gene. This alteration results from a G to A substitution at nucleotide position 343, causing the alanine (A) at amino acid position 115 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
