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]

Sep 01, 2021

The c.125G>A (p.R42Q) alteration is located in exon 1 (coding exon 1) of the EIF2AK4 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the arginine (R) at amino acid position 42 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
