Genes affected

PDCD4 (HGNC:8763): (programmed cell death 4) This gene is a tumor suppressor and encodes a protein that binds to the eukaryotic translation initiation factor 4A1 and inhibits its function by preventing RNA binding. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2010]

The c.737A>T (p.D246V) alteration is located in exon 6 (coding exon 5) of the PDCD4 gene. This alteration results from a A to T substitution at nucleotide position 737, causing the aspartic acid (D) at amino acid position 246 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
