Genes affected

BTG2 (HGNC:1131): (BTG anti-proliferation factor 2) 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 is involved in the regulation of the G1/S transition of the cell cycle.
