[Identification of novel missense mutation G571E, novel silent mutation H229H, nonsense mutation C74X, and four single nucleotide polymorphisms in the low-density lipoprotein receptor in patients with familial hypercholesterolemia from St. Petersburg].

Novel missense mutation G571E (c.1775 G > A), novel silent mutation H229H (c.750 C > T), and nonsense mutation C74X (c.285 C > A), earlier described in Japan but unknown in Russia, were identified in the low-density lipoprotein (LDL) receptor gene in St. Petersburg familial hypercholesterolemia in patients. The analyzed group of patients was shown to be polymorphic in many positions of the LDL receptor gene, namely: c.1171 G/A, c.1773 T/C, c.2177 C/T, and c.2231 G/A.
