Familial hypercholesterolemia (FH) is a very common human hereditary disease in Russia and in the whole world with most of mutations localized in the gene coding for the low density lipoprotein receptor (LDLR). The object of this review is to systematize the knowledge about LDLR mutations in Russia. With this aim we analyzed all available literature on the subject and tabulated the data.

For more than 10 years the research in this field was carried out in Saint-Petersburg, the megapolis in the North-West Russia. Studies were focused on the search for causative mutations in low-density lipoprotein receptor gene ().

This mutation designated c.1327 T>C (W443R [W422R]) was predicted to cause substitution of arginine for tryptophan residue in the very conservative -propeller domain of the LDL receptor.

Subjects And Methods: The examination of 196 patients with FH involved laboratory tests, electrocardiography, echocardiography, triplex scanning of the arteries, exercise testing, and coronarography as indicated. Genetic examination was performed in 109 (55.
Using an automated fluorescent single-strand conformation polymorphism (SSCP) analysis of the entire coding region, promoter zone, and exon-intron junctions of the low-density lipoprotein (LDL) receptor gene, we examined 80 DNA samples of patients with familial hypercholesterolemia (FH) from Petrozavodsk. We revealed mutations that might cause FH in five probands, including FH-North Karelia (c.925-931del7) mutation and four previously unknown mutations.

Aim: To study genetic peculiarities of FHC in Kareliya.
Materials And Methods: 109 patients of the 196 ones with FHC (124 families) were subjected to genetic examination.
Background: Familial hypercholesterolemia (FH) is a human monogenic disease induced by a variety of mutations with striking genetic diversity. Despite this variability recurrent mutations occur in each population studied, which allows both elucidating prevalent mutations and developing DNA diagnostic tools for the disease. Recent research of FH in St.

The FH-North Karelia mutation was found in one family in St.

Proprotein convertase acts as a molecular chaperone for the low density lipoprotein (LDL) receptor, targeting it to the lysosomal degradation pathway. Various mutations increasing the PCSK9 affinity toward the LDL receptor cause autosomal dominant hypercholesterolemia.

Six of them (5382insC, 2963del10, 3819de15, 3875del4, 2274insA, and R1203X) cause premature termination of protein synthesis, thus predisposing to breast cancer. A missense mutation E1250K is presumed to be a factor of predisposition to cancer.
