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 Pathogenic. Variant got 11 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 4.2, offset of 7, new splice context is: tttcctcttttgggtcaaAGagc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 15-39939503-A-G is Pathogenic according to our data. Variant chr15-39939503-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 812856.Status of the report is no_assertion_criteria_provided, 0 stars.
