INTRODUCTION: Ataxia telangiectasia (AT) is an autosomal-recessive disease, characterized by progressive cerebellar degeneration, mucocutaneous telangiectasia, immunodeficiency, recurrent sinopulmonary infections, sensitivity to radiation, and increased risk of malignancy. The objective of this study was to report the clinical profile of a large cohort of patients with AT seen in a tertiary care referral center. METHODS: This study was a chart review of 100 patients with AT seen by the department of neurology at the National Institute of Mental Health and Neurosciences (NIMHANS), Bengaluru, Karnataka, India, which is a tertiary care referral center. Detailed demographic, clinical, laboratory, and electrophysiological data were collected from the case records. RESULTS: The mean age of presentation was 9.04 ± 3.52 years. Females (n = 40) had earlier age of presentation (8.87 ± 3.09 years) when compared to males (9.15 ± 3.80 years). The mean age for onset of illness was 3.9 ± 2.84 years, and the mean duration of illness was 4.81 ± 3.30 years. A positive family history was obtained in 20% and consanguinity in 60%. Oculomotor abnormalities included impaired pursuit and slow saccades in 60%, oculomotor apraxia in 84%, and nystagmus in 23%. All the patients had cerebellar ataxia. Extrapyramidal features such as dystonia, choreoathetosis, tremors, and myoclonus were observed in 31% of patients. CONCLUSION: Progressive cerebellar ataxia and telangiectasias were the consistent findings observed in all our patients. Dystonia and chorea were the other extrapyramidal features observed. Owing to increased risk of malignancies, screening should be an integral part of management.
