Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001037283.2(EIF3B):​c.118C>A​(p.Pro40Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000133 in 149,816 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P40S) has been classified as Uncertain significance.

Genes affected
EIF3B (HGNC:3280): (eukaryotic translation initiation factor 3 subunit B) Enables RNA binding activity. Contributes to translation initiation factor activity. Involved in several processes, including IRES-dependent viral translational initiation; translational initiation; and viral translational termination-reinitiation. Located in extracellular exosome. Part of eukaryotic translation initiation factor 3 complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.118C>A (p.P40T) alteration is located in exon 1 (coding exon 1) of the EIF3B gene. This alteration results from a C to A substitution at nucleotide position 118, causing the proline (P) at amino acid position 40 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
