Genes affected

EIF2S3 (HGNC:3267): (eukaryotic translation initiation factor 2 subunit gamma) The protein encoded by this gene is the largest subunit of a heterotrimeric GTP-binding protein involved in the recruitment of methionyl-tRNA(i) to the 40 S ribosomal subunit. [provided by RefSeq, Jan 2010]
