[Familial defect of apo B-100 in subjects with clinically diagnosed primary hypercholesterolemia: identification of the first family with this disorder in Spain].
BACKGROUND
The aim of our study was to screen mutations responsible of FDB in subjects with primary hypercholesterolemia.


METHODS
We have screened R3500Q and other mutations (PCR-SSCP analysis) in 110 subjects with primary hypercholesterolemia from the Valencia area (Spain), 95 of them with familial hypercholesterolemia (FH) and 15 with poligenic hypercholesterolemia (PHC).


RESULTS
One out of 95 subjects carried the R3500Q mutation. We have searched in the family and have identified another affected subject.


CONCLUSIONS
We have identified the first affected Spanish family from FDB. The prevalence of R3500Q mutations was of 1% in FH subjects in this series.
