Introduction. Approximately 4% of the world's population develops orphan diseases. The vast majority of them have a genetic origin. The main method for studying the semiotics of genetic pathology is syndromic analysis. However, implementation requires a lot of experience and is often subjective. In addition, there are not enough trained clinical geneticists, so the waiting time for an appointment is long. That is why the use of computer programs in the work of a doctor allows for the diagnosis of rare hereditary disorders. Modern computer phenotype identification technology analyses images of people's faces with the help of a program created on the basis of artificial intelligence. The application "Face2Gene" (FDNA Inc., USA) creates a list of genetic pathologies that, in its opinion, the patient may have. Thus, it allows the geneticist to carry out the diagnosis of hereditary pathology much more effectively.
