Genes affected

EIF5 (HGNC:3299): (eukaryotic translation initiation factor 5) Eukaryotic translation initiation factor-5 (EIF5) interacts with the 40S initiation complex to promote hydrolysis of bound GTP with concomitant joining of the 60S ribosomal subunit to the 40S initiation complex. The resulting functional 80S ribosomal initiation complex is then active in peptidyl transfer and chain elongations (summary by Si et al., 1996 [PubMed 8663286]).[supplied by OMIM, May 2010]

Collection Method: clinical testing

The c.424C>T (p.L142F) alteration is located in exon 6 (coding exon 4) of the EIF5 gene. This alteration results from a C to T substitution at nucleotide position 424, causing the leucine (L) at amino acid position 142 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
