Genes affected

EIF4G1 (HGNC:3296): (eukaryotic translation initiation factor 4 gamma 1) The protein encoded by this gene is a component of the multi-subunit protein complex EIF4F. This complex facilitates the recruitment of mRNA to the ribosome, which is a rate-limiting step during the initiation phase of protein synthesis. The recognition of the mRNA cap and the ATP-dependent unwinding of 5'-terminal secondary structure is catalyzed by factors in this complex. The subunit encoded by this gene is a large scaffolding protein that contains binding sites for other members of the EIF4F complex. A domain at its N-terminus can also interact with the poly(A)-binding protein, which may mediate the circularization of mRNA during translation. Alternative splicing results in multiple transcript variants, some of which are derived from alternative promoter usage. [provided by RefSeq, Aug 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.193C>T (p.P65S) alteration is located in exon 6 (coding exon 4) of the EIF4G1 gene. This alteration results from a C to T substitution at nucleotide position 193, causing the proline (P) at amino acid position 65 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
