Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PS1_Moderate PM1 PM2 PM5 PP2 PP3 PP5_Moderate

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. Variant has been reported in ClinVar as Pathogenic (★). 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 12 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 10 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
• PP5: Variant 17-7311395-G-A is Pathogenic according to our data. Variant chr17-7311395-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 3369240.Status of the report is criteria_provided_single_submitter, 1 stars.
