Genes affected

EIF2D (HGNC:6583): (eukaryotic translation initiation factor 2D) This gene encodes a translation initiation factor involved in the recruitment and delivery of aminoacyl-tRNAs to the P-site of the eukaryotic ribosome in a GTP-independent manner. This gene was previously referred to as ligatin, but is now known to localize to the cytoplasm and localize and function with translation factors. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

The c.1580G>A (p.R527Q) alteration is located in exon 14 (coding exon 14) of the EIF2D gene. This alteration results from a G to A substitution at nucleotide position 1580, causing the arginine (R) at amino acid position 527 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
