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.227C>T (p.S76L) alteration is located in exon 3 (coding exon 2) of the PDCD4 gene. This alteration results from a C to T substitution at nucleotide position 227, causing the serine (S) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
