Genes affected

GLRX3 (HGNC:15987): (glutaredoxin 3) This gene encodes a member of the glutaredoxin family. Glutaredoxins are oxidoreductase enzymes that reduce a variety of substrates using glutathione as a cofactor. The encoded protein binds to and modulates the function of protein kinase C theta. The encoded protein may also inhibit apoptosis and play a role in cellular growth, and the expression of this gene may be a marker for cancer. Pseudogenes of this gene are located on the short arm of chromosomes 6 and 9. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Dec 2010]

The c.442C>G (p.L148V) alteration is located in exon 4 (coding exon 4) of the GLRX3 gene. This alteration results from a C to G substitution at nucleotide position 442, causing the leucine (L) at amino acid position 148 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
