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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EIF4G1. . Gene score misZ 2.2233 (greater than the threshold 3.09). Trascript score misZ 4.0613 (greater than threshold 3.09). GenCC has associacion of gene with Parkinson disease 18, autosomal dominant, susceptibility to.
BP4
Computational evidence support a benign effect (MetaRNN=0.22073391).

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2023The c.104C>A (p.T35K) alteration is located in exon 4 (coding exon 2) of the EIF4G1 gene. This alteration results from a C to A substitution at nucleotide position 104, causing the threonine (T) at amino acid position 35 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
