Acute-phase and convalescent-phase sera of 66 children, aged 3 months to 12 years, with neurologic disorders of unknown etiology were tested against Legionella pneumophila polyvalent and monovalent antigens (groups 1 to 4). Three significant antibody titer increases were obtained, all in children with acute cerebellar ataxia. This neurologic syndrome was characterized by sudden onset of muscle hypotonia and inability to sit or walk, with no other specific neurologic or systemic symptoms. Persisting pharyngitis always preceded ataxia. Fever of short duration was still present. Gastrointestinal disturbance occurred in two of the three children. Abnormal laboratory findings were, not always simultaneously, high ESR and leukocytosis with lymphocytosis. CSF levels and electromyographic findings were normal in two of the children. Two children received oral betamethasone. Recovery was complete within seven to ten days without antibiotic treatment. These studies indicate the possible etiologic role of L pneumophila in acute cerebellar ataxia.

Interstitial deletions in the terminal region of chromosome 6 are rare. We describe three new cases with subtle interstitial deletions in the q24-q26 region of the long arm of chromosome 6. The karyotypes were analyzed at a 550 band level. Patient1 is a 9-month-old boy with an interstitial deletion, del(6)(q24.2q25.1), developmental delay, low birth weight, hypotonia, heart murmur, respiratory distress, craniofacial and genital anomalies. This is the first report of a case with deletion del(6)(q24.2q25.1). Patient 2 is a 17-year-old young man with an interstitial deletion del(6)(q25.1q25.3), developmental delay, short stature, mental retardation, autism, head, face, chest, hand and feet anomalies and a history of seizures. For the first time autism was described as a manifestation in 6q deletions. Patient 3 is baby boy with a de novo interstitial deletion, del(6)(q25.1q26), anomalies of the brain, genital organs, limbs and feet. This is the first report of a case with deletion, del(6)(q25.1q26). In all three patients, fluorescence in situ hybridization (FISH) using chromosome 6 painting probe ruled out an insertion. The ESR (6q25.1) and TBP (6q27) probes were used to confirm the breakpoints. Since TBP signal is present in all cases, it confirmed an interstitial deletion proximal to this probe. Patient 1 has a deletion of the ESR locus; Patient 2 and 3 have signals for the ESR locus on both chromosomes 6. Therefore the deletion in Patients 2 and 3 are between ESR and TBP loci distal to that of Patient 1. FISH validated the deletion breakpoints assessed by conventional cytogenetics.
