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]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.33304542).

The c.561G>A (p.M187I) alteration is located in exon 6 (coding exon 5) of the PDCD4 gene. This alteration results from a G to A substitution at nucleotide position 561, causing the methionine (M) at amino acid position 187 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
