Four of the families, pedigrees A–D (table 1), were consanguineous. In total there were 16 living affected individuals, aged 3–25 years. All had cone rod dystrophy that presented in the first 3 months of life with photophobia and nystagmus. The cone rod dystrophy progressed and all were registered blind by the end of the first decade. By the middle of the first decade a characteristic appearance of sunken eyes and a prominent supra-orbital ridge had developed (fig 1A). Truncal obesity became apparent in the first few years of life and all exhibited acanthosis nigricans in their teenage years. None has yet developed symptomatic diabetes. All males of sufficient age failed to enter puberty without hormone support and thereafter developed a female fat distribution (fig 1B). Deafness developed in all cases by the end of the first decade, but varied in severity and symmetry within and between families. All affected individuals were of normal intelligence though they experienced educational difficulties because of their combined and progressive sensory deficits. In all seven families other diagnoses had been made prior to the final diagnosis of Alström syndrome, presumably because of the rarity of the condition and the sequential presentation of disease features.1,2View this table:In this windowIn a new window Table 1  Mutations in ALMS1 causing premature protein truncation in Alström syndrome patients exhibiting early onset cardiomyopathy Figure 1  Face and body habitus of a study patient with Alström syndrome.
