Genes affected

BTG4 (HGNC:13862): (BTG anti-proliferation factor 4) The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein can induce G1 arrest in the cell cycle. [provided by RefSeq, Jul 2008]
