Genes affected
TSPAN3 (HGNC:17752): (tetraspanin 3) 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. The use of alternate polyadenylation sites has been found for this gene. Multiple alternative transcripts encoding different isoforms have been described. [provided by RefSeq, Dec 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.694A>G (p.I232V) alteration is located in exon 7 (coding exon 7) of the TSPAN3 gene. This alteration results from a A to G substitution at nucleotide position 694, causing the isoleucine (I) at amino acid position 232 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
