BACKGROUND: As is often the case for rare diseases, the number of published
reviews and case reports of glucose transporter type I deficiency (G1D)
approaches or exceeds that of original research. This can indicate medical
interest, but also scientific stagnation. METHODS: In assessing this state of
affairs here, we focus not on what is peculiar or disparate about G1D, but on the
assumptions that have reigned thus far undisputed, and critique them as a
potential impediment to progress. To summarize the most common G1D phenotype, we
trace the 25-year story of G1D in parallel with the natural history of one of two
index patients, identified in 1990 by one of us (G.M.R.) and brought up to date
by the other (J.M.P.) while later examining widely repeated but
little-scrutinized statements. Among them are those that pertain to assumptions
about brain fuels; energy failure; cerebrospinal glucose concentration; the
purpose of ketogenic diet; the role of the defective blood-brain barrier;
genotype-phenotype correlations; a bewildering array of phenotypes; ictogenesis,
seizures, and the electroencephalograph; the use of mice to model the disorder;
and what treatments may and may not be expected to accomplish. RESULTS: We reach
the forgone conclusion that the proper study of mankind-and of one of its
ailments (G1D) -is man itself (rather than mice, isolated cells, or extrapolated
inferences) and propose a framework for rigorous investigation that we hope will
lead to a better understanding and to better treatments for this and for rare
disorders in general. CONCLUSIONS: These considerations, together with experience
drawn from other disorders, lead, as a logical consequence, to the nullification
of the view that therapeutic development (i.e., trials) for rare diseases could
or should be accelerated without the most vigorous scientific scrutiny: trial and
error constitute an inseparable couple, such that, at the present time, hastening
the former is bound to precipitate the latter.
