Genes affected

SLC16A7 (HGNC:10928): (solute carrier family 16 member 7) This gene is a member of the monocarboxylate transporter family. Members in this family transport metabolites, such as lactate, pyruvate, and ketone bodies. The protein encoded by this gene catalyzes the proton-linked transport of monocarboxylates and has the highest affinity for pyruvate. This protein has been reported to be more highly expressed in prostate and colorectal cancer specimens when compared to control specimens. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]

The c.1034T>A (p.V345E) alteration is located in exon 4 (coding exon 3) of the SLC16A7 gene. This alteration results from a T to A substitution at nucleotide position 1034, causing the valine (V) at amino acid position 345 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
