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]

Jun 07, 2023

The c.32T>C (p.L11S) alteration is located in exon 1 (coding exon 1) of the EIF2B2 gene. This alteration results from a T to C substitution at nucleotide position 32, causing the leucine (L) at amino acid position 11 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
