Genes affected
TM4SF1 (HGNC:11853): (transmembrane 4 L six family member 1) 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. This encoded protein is a cell surface antigen and is highly expressed in different carcinomas. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.235T>C (p.C79R) alteration is located in exon 2 (coding exon 2) of the TM4SF1 gene. This alteration results from a T to C substitution at nucleotide position 235, causing the cysteine (C) at amino acid position 79 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
