Genes affected

EIF3F (HGNC:3275): (eukaryotic translation initiation factor 3 subunit F) Enables deubiquitinase activity and identical protein binding activity. Contributes to translation initiation factor activity. Involved in IRES-dependent viral translational initiation; protein deubiquitination; and translational initiation. Located in membrane. Part of eukaryotic translation initiation factor 3 complex. Implicated in autosomal recessive non-syndromic intellectual disability. [provided by Alliance of Genome Resources, Apr 2022]

EIF3F Gene-Disease associations (from GenCC):

• syndromic intellectual disability

  Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
• intellectual developmental disorder, autosomal recessive 67

  Inheritance: Unknown, AR Classification: STRONG, MODERATE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
