Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_003754.3(EIF3F):​c.19C>A​(p.Pro7Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000125 in 1,595,852 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P7S) has been classified as Likely benign.

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

ACMG classification
