A dominant ELOVL1 mutation causes a neuro-ichthyotic disorder possibly amenable to treatment with PPAR-modulating drugs.
Title: De novo mutation in ELOVL1 causes ichthyosis, acanthosis nigricans, hypomyelination, spastic paraplegia, high frequency deafness and optic atrophy.
he ELOVL1 p.Ser165Phe mutation is a likely cause of ichthyotic keratoderma, spasticity, mild hypomyelination (on MRI) and dysmorphic features (IKSHD).
Title: Dominant ELOVL1 mutation causes neurological disorder with ichthyotic keratoderma, spasticity, hypomyelination and dysmorphic features.
ELOV1 promotes very long-chain fatty acid accumulation X-linked adrenoleukodystrophy and is inhibited by CoA esters of bezafibrate and gemfibrozil.
Title: Enzymatic characterization of ELOVL1, a key enzyme in very long-chain fatty acid synthesis.
Results suggest that inhibition of atty acid elongase 1 (ELOVL1) may be an underlying mechanism by which Lorenzo's oil exerts its action.
Title: Lorenzo's oil inhibits ELOVL1 and lowers the level of sphingomyelin with a saturated very long-chain fatty acid.
down-regulation of ELOVL1 had a comprehensive effect on the synthesis of very long chain ceramides which possibly point to a requirement for ELOVL1 expression for full CerS2-activity.
Title: The equilibrium between long and very long chain ceramides is important for the fate of the cell and can be influenced by co-expression of CerS.
ELOVL1 activity is regulated with the ceramide synthase CERS2, an enzyme essential for C24 sphingolipid synthesis.
Title: ELOVL1 production of C24 acyl-CoAs is linked to C24 sphingolipid synthesis.
The authors identify ELOVL1 (elongation of very-long-chain-fatty acids) as the single elongase catalysing the synthesis of both saturated VLCFA (C26:0) and mono-unsaturated VLCFA (C26:1).
Title: The role of ELOVL1 in very long-chain fatty acid homeostasis and X-linked adrenoleukodystrophy.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NR_046117.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (5) lacks an alternate exon and uses a different splice site, compared to variant 1. This variant is represented as non-coding because the use of the translational start codon as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
