Hereditary disease, included under number 154700 in the McKusick OMIM tabulation system. The disease has multiple organ manifestations. In addition to characteristic changes in the organs of the musculoskeletal system (elongated skeletal bones, hypermobility of joints), pathology is observed in the organs of vision and the cardiovascular system, which constitutes the classic triad.

(trisomy on chromosome 21) is one of the forms of genomic pathology, in which most often the karyotype is represented by 47 chromosomes instead of the normal 46, since the chromosomes of the 21st pair, instead of the normal two, are represented by three copies (trisomy, see also Ploidy). There are two more forms of this syndrome: translocation of chromosome 21 to other chromosomes (usually on 15, less often on 14, even less often on 21, 22 and Y chromosome) - 4% of cases, and a mosaic variant of the syndrome - 5%.

Medical genetic consultation consists of 4 stages; diagnosis, prognosis, conclusion, advice. In this case, frank and friendly communication between the geneticist and the patient’s family is necessary. Consultation always begins with clarifying the diagnosis of a hereditary disease, since an accurate diagnosis is a necessary prerequisite for any consultation. The attending physician, before referring the patient to medical genetic consultation, must, using the methods available to him, clarify the diagnosis as much as possible and determine the purpose of the consultation. It is also necessary to use genealogical, cytogenetic, biochemical and other special genetic methods (for example, to determine the linkage of genes or use molecular genetic methods, etc.).

HUMAN GENETICS

MAN AS AN OBJECT OF GENETIC RESEARCH Difficulties in studying human heredity and variability. Impossibility of directed crosses. Late puberty. Few offspring. The impossibility of providing identical and strictly controlled conditions for the development of offspring from different marriages. Relatively large number of chromosomes. Impossibility of conducting direct experiments. Conclusion: the study of human heredity requires the use of special research methods.

METHODS FOR STUDYING HUMAN GENETICS Genealogical (studying pedigrees and identifying the type of inheritance). Cytogenetic (analysis of karyotype in normal and pathological conditions). Biochemical method (study of gene structures). Twin method (study of identical twins and the influence of environmental factors on the genotype). Immunogenetic method (genetics of blood groups).

PRACTICAL GENETICS Genealogical. Cytogenetic. Biochemical. Twin. Immunogenetic. Down syndrome. Lack of Rh factor in the blood. Hemophilia. Phenylketonuria. Albinism. Turner syndrome. Diabetes. Cleft lip. Polydactyly. Correlate the research method and the human genetic disease.

METHODS FOR DISEASE DETECTION Genealogical method - polydactyly, hemophilia, albinism. Biochemical method – diabetes mellitus, phenylketonuria, sickle cell anemia. Cytogenetic method – Down syndrome, Turner syndrome, cleft lip. Immunogenetic method - identification of blood groups, the presence of the Rh factor. The twin method examines the manifestation of characteristics, for example, blood type, eye and hair color are completely determined genetically.

A MASTERPIECE WITH A HEREDITARY ANOMALY In Raphael’s painting “The Sistine Madonna” to the left of Mary is Pope Sic c t II. Find a genetic disorder. Determine the type of inheritance. * Many church ministers, having seen the canvas, claimed that it was created by the devil, since they saw the number of the beast... The Pope has 6 fingers on his right hand. Hence the name - Sixtus. There are 6 characters in the picture.

HISTORICAL CHRONICLES The son of the last Emperor of Russia, Tsarevich Alexei, suffered from a hereditary disease - hemophilia. Prove that Queen Victoria of England has a direct connection to this.
