Abstract
Alpha-mannosidosis is an autosomal recessive disorder caused by deficiency of lysosomal α-mannosidase (LAMAN). Here, we report two sisters with α-mannosidosis who developed systemic lupus erythematosus (SLE). The sisters were both homozygous for a one bp deletion within the LAMAN gene resulting in a truncated gene product. The coincidence of α-mannosidosis and SLE are discussed with regard to both clinical and molecular findings. Conclusion:α-mannnosidosis may contribute to the onset of systemic lupus erythematosus in predisposed patients.
