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.
