What's a GeneRIF?

results show that NAXD deficiency can be classified as a metabolite repair disorder in which accumulation of damaged metabolites likely triggers devastating effects in tissues such as the brain and the heart, eventually leading to early childhood death.

Wide tissue distribution of dehydratase and epimerase is consistent with mRNA data for Carkd and Aibp, and their presence in both mitochondria and cytosol is explained by the existence of differently targeted forms of CARKD and AIBP.

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.
