Genes affected

PRDX4 (HGNC:17169): (peroxiredoxin 4) The protein encoded by this gene is an antioxidant enzyme and belongs to the peroxiredoxin family. The protein is localized to the cytoplasm. Peroxidases of the peroxiredoxin family reduce hydrogen peroxide and alkyl hydroperoxides to water and alcohol with the use of reducing equivalents derived from thiol-containing donor molecules. This protein has been found to play a regulatory role in the activation of the transcription factor NF-kappaB. [provided by RefSeq, Jul 2008]

The c.535G>C (p.D179H) alteration is located in exon 4 (coding exon 4) of the PRDX4 gene. This alteration results from a G to C substitution at nucleotide position 535, causing the aspartic acid (D) at amino acid position 179 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
