Genes affected

EIF4A2 (HGNC:3284): (eukaryotic translation initiation factor 4A2) Enables ATP hydrolysis activity. Involved in negative regulation of RNA-directed 5'-3' RNA polymerase activity. Located in perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

EIF4A2 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with hypotonia and speech delay, with or without seizures

  Inheritance: AR, AD Classification: STRONG, MODERATE, LIMITED Submitted by: G2P, Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 8 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 3.895 (above the threshold of 3.09). Trascript score misZ: 5.45 (above the threshold of 3.09). GenCC associations: The gene is linked to neurodevelopmental disorder with hypotonia and speech delay, with or without seizures.
