To the Editor:
The report by Blesa et al. (1) compares 2 methods, DNA sequencing and DNA arrays [as previously reported by us (2)], for the genetic diagnosis of familial hypercholesterolemia (FH).
Lipochip® (Lacer SA), the first DNA array-based commercial platform for the genetic diagnosis of FH, is now available and is funded by the Spanish Health Service. The procedure is as follows: blood samples are shipped to a central laboratory, where DNA is analyzed with the first CE-marked (approved for sale in the European Community) DNA array for in vitro diagnosis in Europe. Samples with a negative result undergo large rearrangement analysis by quantitative fluorescence-based multiplex PCR (3). If this analysis is also negative, DNA sequencing is carried out to identify new disease-causing variations. The results are compiled in a full report that is sent to the patients physician.
Most of the comments by Blesa et al. on our DNA array refer
