Genes affected

SLC46A3 (HGNC:27501): (solute carrier family 46 member 3) The protein encoded by this gene is a member of a transmembrane protein family that transports small molecules across membranes. The encoded protein has been found in lysosomal membranes, where it can transport catabolites from the lysosomes to the cytoplasm. This protein has been shown to be an effective transporter of the cytotoxic drug maytansine, which is used in antibody-based targeting of cancer cells. [provided by RefSeq, Dec 2016]

Ambry Genetics

Jun 10, 2022

The c.535G>C (p.V179L) alteration is located in exon 3 (coding exon 2) of the SLC46A3 gene. This alteration results from a G to C substitution at nucleotide position 535, causing the valine (V) at amino acid position 179 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
