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=0.19648796).
