Genes affected

EIF4E (HGNC:3287): (eukaryotic translation initiation factor 4E) The protein encoded by this gene is a component of the eukaryotic translation initiation factor 4F complex, which recognizes the 7-methylguanosine cap structure at the 5' end of messenger RNAs. The encoded protein aids in translation initiation by recruiting ribosomes to the 5'-cap structure. Association of this protein with the 4F complex is the rate-limiting step in translation initiation. This gene acts as a proto-oncogene, and its expression and activation is associated with transformation and tumorigenesis. Several pseudogenes of this gene are found on other chromosomes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 4-98881149-G-GA is Benign according to our data. Variant chr4-98881149-G-GA is described in ClinVar as [Benign]. Clinvar id is 781716.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0171 (16442/962200) while in subpopulation EAS AF= 0.0448 (1043/23286). AF 95% confidence interval is 0.0425. There are 0 homozygotes in gnomad4_exome. There are 8522 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 71 AD gene.
