Genes affected

EIF2B2 (HGNC:3258): (eukaryotic translation initiation factor 2B subunit beta) This gene encodes the beta subunit of eukaryotic initiation factor-2B (EIF2B). EIF2B is involved in protein synthesis and exchanges GDP and GTP for its activation and deactivation. [provided by RefSeq, Aug 2011]
