Genes affected
TM9SF2 (HGNC:11865): (transmembrane 9 superfamily member 2) This gene encodes a member of the transmembrane 9 superfamily. The encoded 76 kDa protein localizes to early endosomes in human cells. The encoded protein possesses a conserved and highly hydrophobic C-terminal domain which contains nine transmembrane domains. The protein may play a role in small molecule transport or act as an ion channel. A pseudogene associated with this gene is located on the X chromosome. [provided by RefSeq, Oct 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.19G>C (p.V7L) alteration is located in exon 1 (coding exon 1) of the TM9SF2 gene. This alteration results from a G to C substitution at nucleotide position 19, causing the valine (V) at amino acid position 7 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
