Genes affected

EIF2A (HGNC:3254): (eukaryotic translation initiation factor 2A) This gene encodes a eukaryotic translation initiation factor that catalyzes the formation of puromycin-sensitive 80 S preinitiation complexes and the poly(U)-directed synthesis of polyphenylalanine at low concentrations of Mg2+. This gene should not be confused with eIF2-alpha (EIF2S1, Gene ID: 1965), the alpha subunit of the eIF2 translation initiation complex. Although both of these proteins function in binding initiator tRNA to the 40 S ribosomal subunit, the encoded protein does so in a codon-dependent manner, whereas eIF2 complex requires GTP. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016]

SERP1 links:

SERP1 (HGNC:10759): (stress associated endoplasmic reticulum protein 1) Predicted to be involved in endoplasmic reticulum unfolded protein response and protein glycosylation. Predicted to act upstream of or within several processes, including multicellular organism aging; positive regulation of organ growth; and positive regulation of peptide hormone secretion. Located in cytoplasmic microtubule. [provided by Alliance of Genome Resources, Apr 2022]

The c.712A>G (p.I238V) alteration is located in exon 9 (coding exon 9) of the EIF2A gene. This alteration results from a A to G substitution at nucleotide position 712, causing the isoleucine (I) at amino acid position 238 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
