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]

Progressive encephalopathy with leukodystrophy due to DECR deficiency Pathogenic:1Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 07, 2022In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 453290). Disruption of the initiator codon has been observed in individual(s) with clinical features of 2,4-dienoyl CoA reductase 1 deficiency (PMID: 29388319). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change affects the initiator methionine of the NADK2 mRNA. The next in-frame methionine is located at codon 164. -
