Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PS1_Moderate PM1 PM2 PM5 PP2 PP3

The NM_001970.5(EIF5A):​c.316G>A​(p.Gly106Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G106?) has been classified as Pathogenic.

Genes affected

EIF5A (HGNC:3300): (eukaryotic translation initiation factor 5A) Enables U6 snRNA binding activity and protein N-terminus binding activity. Involved in several processes, including cellular response to virus; positive regulation of intrinsic apoptotic signaling pathway by p53 class mediator; and tumor necrosis factor-mediated signaling pathway. Located in annulate lamellae; cytoplasm; and nucleus. Part of nuclear pore. [provided by Alliance of Genome Resources, Apr 2022]

GPS2 (HGNC:4550): (G protein pathway suppressor 2) This gene encodes a protein involved in G protein-mitogen-activated protein kinase (MAPK) signaling cascades. When overexpressed in mammalian cells, this gene could potently suppress a RAS- and MAPK-mediated signal and interfere with JNK activity, suggesting that the function of this gene may be signal repression. The encoded protein is an integral subunit of the NCOR1-HDAC3 (nuclear receptor corepressor 1-histone deacetylase 3) complex, and it was shown that the complex inhibits JNK activation through this subunit and thus could potentially provide an alternative mechanism for hormone-mediated antagonism of AP1 (activator protein 1) function.

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PS1: Transcript NM_001970.5 (EIF5A) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a chain Eukaryotic translation initiation factor 5A-1 (size 152) in uniprot entity IF5A1_HUMAN there are 16 pathogenic changes around while only 0 benign (100%) in NM_001970.5
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr17-7311395-G-M is described in Lovd as [Pathogenic].
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EIF5A. . Gene score misZ 2.407 (greater than the threshold 3.09). Trascript score misZ 4.4819 (greater than threshold 3.09). GenCC has associacion of gene with Faundes-Banka syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.838
