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]

Ambry Genetics

Nov 21, 2023

The c.434G>A (p.S145N) alteration is located in exon 4 (coding exon 4) of the TM9SF2 gene. This alteration results from a G to A substitution at nucleotide position 434, causing the serine (S) at amino acid position 145 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
