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]

The c.175G>A (p.E59K) alteration is located in exon 2 (coding exon 2) of the TM9SF2 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the glutamic acid (E) at amino acid position 59 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
