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]

The EIF4G1 c.475G>T variant is predicted to result in the amino acid substitution p.Ala159Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0059% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-184037527-G-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
