title: [AMP deaminase deficiency (myoadenylate deaminase). Disease or syndrome?].
abstract: Two recent publications have shown the advantage of understanding the deficit in AMP desaminase in rheumatology. On this subject, the authors report 4 cases of deficit in AMP desaminase. The first one includes a semiology made of pain, and stiffening, the second case is discovered in the course of a primary muscular disease. The third case is present during the first stage of a spinal cord compression. The fourth case is a muscular deficit accompanied with a histological picture of inflammation, considered initially as a chronic polymyositis, but explained secondarily as a pseudo-polymyositis form of facio-scapulo-humeral dystrophy. In this respect, the cases from the literature are divided into three groups: asymptomatic, infraclinical forms, forms occurring in the course of specific diseases (muscular diseases, spinal cord diseases, inflammations of the connective tissues, metabolic diseases), apparently isolated forms. In the latter, emerges a semiology made of pain, cramps, stiffening of the lower extremities occurring on exertion. However, the specificity of the symptoms remains to be discussed.
