Lipodystrophy_Lipoatrophy v0.83 PSMB8 Zornitza Stark changed review comment from: This autosomal recessive systemic autoinflammatory disorder is characterized by early childhood onset of annular erythematous plaques on the face and extremities with subsequent development of partial lipodystrophy and laboratory evidence of immune dysregulation. More variable features include recurrent fever, severe joint contractures, muscle weakness and atrophy, hepatosplenomegaly, basal ganglia calcifications, and microcytic anaemia.

This disorder encompasses Nakajo-Nishimura syndrome (NKJO); joint contractures, muscular atrophy, microcytic anemia, and panniculitis-induced lipodystrophy (JMP syndrome); and chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome (CANDLE).

More than 10 molecularly confirmed cases reported.

Digenic inheritance has been proposed in some individuals with variants in other PSMB genes.; to: This autosomal recessive systemic autoinflammatory disorder is characterized by early childhood onset of annular erythematous plaques on the face and extremities with subsequent development of partial lipodystrophy and laboratory evidence of immune dysregulation.

Review for gene: PSMB4 was set to AMBER
Added comment: Proteasome-associated autoinflammatory syndrome-3 is an autosomal recessive syndrome with onset in early infancy. Affected individuals present with nodular dermatitis, recurrent fever, myositis, panniculitis-induced lipodystrophy, lymphadenopathy, and dysregulation of the immune response, particularly associated with abnormal type I interferon-induced gene expression patterns. Additional features are highly variable, but may include joint contractures, hepatosplenomegaly, anaemia, thrombocytopaenia, recurrent infections, autoantibodies, and hypergammaglobulinaemia. Some may have intracranial calcifications.

One individual with bi-allelic variants, and two others with mono-allelic variants in PSMB4 as well as variants in PSMB9 or PSMB8, digenic model proposed.
