Abstract

Alstrom syndrome (Online Mendelian Inheritance in Man ALMS #203800) is a rare hereditary disorder caused by mutations in the gene ALMS1. This rare disorder's characteristics are cone-rod dystrophy resulting in blindness in childhood, insulin-resistant type 2 diabetes mellitus, truncal obesity, progressive sensorineural hearing loss, dilated cardiomyopathy, craniofacial features, hypothyroidism, elevation in liver transaminases, renal insufficiency, gonadal dysfunction, and menstrual irregularities. A 13.5-year-old girl was admitted to the hospital for complaints of excessive water consumption and urination over the previous 2 years. The patient's parents were third-degree relatives. At physical examination, hyperpigmentation was present over the areola and acanthosis nigricans under the arms and on the neck. Audio-logic examination revealed bilateral sensorineural hearing loss, and bilateral cataract was determined at ocular examination. The patient was monitored by the chest diseases department due to bronchiectasis. HbA1c was 13.1%. In mutation screening study, 2 novel mutations c.5586T > G; p.Tyr1862* and c.2905insT; p.L968fs*4 were detected in the ALMS1 gene. Saccharin test was positive. We emphasize that Alstrom syndrome may be complicated by bronchiectasis.
