NUS1

Nuclear undecaprenyl pyrophosphate synthase 1 homolog (NUS1), or dehydrodolichyl diphosphate synthase complex subunit NUS1, or Nogo-B receptor (NgBR) is a protein that in humans is encoded by the NUS1 gene.^[5] Mutations within the NUS1 gene lead to a diagnosis of an NUS1 genetic disorder.^[6]

Gene

In humans NUS1 is located on is a chromosome 6q22.1.^[5]

Clinical signficance

If both copies of the NUS1 gene bear a mutation, the severe and rare disorder NUS1-CDG can occur. However, most patients only present with a mutation on one copy of the gene; this nevertheless causes a progressive neurological condition.^[6] Mutations of the NUS1 gene are associated with epilepsy, intellectual disability, and mild cerebellar ataxia.^[7]

NUS1 has been identified as a potential candidate gene for Parkinson's disease in Han Chinese people.^[8]
