Overview of Nakajo–Nishimura Syndrome

The Nakajo–Nishimura Syndrome is a rare hereditary autoinflammatory disorder with lipodystrophy caused by a homozygous mutation of the PSMB8 gene.​

The Nakajo–Nishimura Syndrome, also known as NNS, is a rare hereditary autoinflammatory disorder with lipodystrophy caused by a homozygous mutation in the PSMB8 gene. This syndrome is characterized by features such as periodic fever٫ pernio-like rash٫ and nodular erythema-like eruptions٫ particularly affecting the upper body.​ It is a distinct inflammatory condition often associated with proteasome dysfunction٫ leading to the overproduction of inflammatory cytokines and chemokines.​

Definition and Background

The Nakajo–Nishimura Syndrome (NNS) is a rare hereditary autoinflammatory disorder with lipodystrophy caused by a homozygous mutation in the PSMB8 gene, leading to characteristics such as periodic fever, pernio-like rash, and nodular erythema-like eruptions.​

PSMB8 Gene Mutation

Nakajo-Nishimura syndrome is specifically associated with a distinct homozygous mutation in the PSMB8 gene, which encodes the immunoproteasome subunit beta 5i.​ This gene alteration leads to the characteristic autoinflammatory features observed in individuals with this syndrome.

Clinical Features of Nakajo–Nishimura Syndrome

Nakajo-Nishimura Syndrome presents with distinctive clinical features including periodic fever, pernio-like rash, and nodular erythema-like eruptions, often affecting the upper body.​

Symptoms and Manifestations

Nakajo-Nishimura Syndrome typically presents with symptoms such as periodic fever, pernio-like rash, and nodular erythema-like eruptions, particularly affecting the upper body.​ Additional manifestations may include lipodystrophy and muscle atrophy.​

Diagnosis and Differential Diagnosis

The diagnosis of Nakajo-Nishimura Syndrome involves recognizing key clinical features such as periodic fever, pernio-like rash, and nodular erythema-like eruptions, along with genetic testing to confirm the PSMB8 gene mutation.​

Diagnostic Approaches

Diagnosing Nakajo-Nishimura Syndrome involves a comprehensive clinical evaluation to identify key symptoms like periodic fever, pernio-like rash, and nodular erythema-like eruptions. Confirmation often requires genetic testing to detect the specific mutation in the PSMB8 gene linked to this rare autoinflammatory disorder.​
