Genes affected
EIF2AK4 (HGNC:19687): (eukaryotic translation initiation factor 2 alpha kinase 4) This gene encodes a member of a family of kinases that phosphorylate the alpha subunit of eukaryotic translation initiation factor-2 (EIF2), resulting in the downregulaton of protein synthesis. The encoded protein responds to amino acid deprivation by binding uncharged transfer RNAs. It may also be activated by glucose deprivation and viral infection. Mutations in this gene have been found in individuals suffering from autosomal recessive pulmonary venoocclusive-disease-2. [provided by RefSeq, Mar 2014]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), EIF2AK4. . Gene score misZ 2.6675 (greater than the threshold 3.09). Trascript score misZ 3.5194 (greater than threshold 3.09). GenCC has associacion of gene with pulmonary venoocclusive disease 2, pulmonary venoocclusive disease, heritable pulmonary arterial hypertension, pulmonary veno-occlusive disease and/or pulmonary capillary haemangiomatosis.
BP4
Computational evidence support a benign effect (MetaRNN=0.12788701).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.47C>T (p.P16L) alteration is located in exon 1 (coding exon 1) of the EIF2AK4 gene. This alteration results from a C to T substitution at nucleotide position 47, causing the proline (P) at amino acid position 16 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
