Natural History
A wide range of clinical variability is observed among individuals with Alström syndrome, including among siblings. The first clinical presentation of Alström syndrome is usually nystagmus caused by cone-rod dystrophy and resulting in childhood blindness. Disease characteristics that are later in onset include truncal obesity that manifests during the first year of life, progressive sensorineural hearing loss, infantile-onset dilated cardiomyopathy or later-onset restrictive cardiomyopathy, insulin-resistant type 2 diabetes mellitus, and hepatic, pulmonary, and renal dysfunction.
