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]

Ambry Genetics

Jun 18, 2021

The c.5C>T (p.P2L) alteration is located in exon 1 (coding exon 1) of the EIF2B2 gene. This alteration results from a C to T substitution at nucleotide position 5, causing the proline (P) at amino acid position 2 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
