Genes affected

NADK2 (HGNC:26404): (NAD kinase 2, mitochondrial) This gene encodes a mitochondrial kinase that catalyzes the phosphorylation of NAD to yield NADP. Mutations in this gene result in 2,4-dienoyl-CoA reductase deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

NADK2 Gene-Disease associations (from GenCC):

• progressive encephalopathy with leukodystrophy due to DECR deficiency

  Inheritance: AR Classification: MODERATE, SUPPORTIVE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), Orphanet, ClinGen, Ambry Genetics

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (REVEL=0.036).
• BP6: Variant 5-36197555-A-G is Benign according to our data. Variant chr5-36197555-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 1639639.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.368 with no splicing effect.
