ABSTRACT
BACKGROUND:
The coexistence of an autoimmune disease and amyotrophic lateral sclerosis (ALS) has led to the hypothesis that immune-mediated pathological mechanisms are overlapping in the two diseases. We report herein a rare coexistence of bullous pemphigoid (BP) in a novel mutation (F45S) of the gene encoding Cu/Zn superoxide dismutase (SOD1) in an ALS patient, and discuss a role for the SOD1 mutation in this unusual overlap. CASE REPORT A 57-year-old male with familial ALS, including vesicles and tense bullae on erythematous bases, was diagnosed with BP. Direct immunofluorescence revealed deposits of C3 and immunoglobulin G in the basement membrane zone. Direct sequencing of SOD1 in the patient revealed a novel mutation (c.137T>C; F45S).CONCLUSIONS:
We report a novel SOD1 mutation in ALS, which was combined with BP. This novel SOD1 mutation could affect the phenotype of a combined autoimmune disease and matrix metalloproteinase-9. There may therefore be common factors linking BP and ALS with the SOD1 mutation.Palabras clave
