    Spinal muscular atrophy is one of the most severe hereditary neuromuscular diseases and one of the main causes of infant mortality caused by hereditary diseases. Being a monogenic disease, SMA is characterized by a wide range of phenotypes, which are based on the influence of genetic modifiers of the disease. These modifiers determine the development of a more severe or milder form of the disease and can act as potential targets of disease therapy. To date, there are three certified drugs for the treatment of SMA, the action of two of them is directed at the transcript of the main modifier of the disease the SMN2 gene. With the advent of effective therapy, the issue of screening newborns for the purpose of early detection of patients and the beginning of treatment of SMA at the presymptomatic phase to achieve maximum effectiveness of drugs becomes relevant. In addition to neonatal screening, population screening plays an important role, which may result in a decrease in the frequency of births of children with SMA.Бпинальная ΠΌΡ‹ΡˆΠ΅Ρ‡Π½Π°Ρ атрофия (БМА) являСтся ΠΎΠ΄Π½ΠΈΠΌ ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ тяТСлых наслСдствСнных Π½Π΅Ρ€Π²Π½ΠΎ-ΠΌΡ‹ΡˆΠ΅Ρ‡Π½Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ ΠΈ ΠΎΠ΄Π½ΠΎΠΉ ΠΈΠ· основных ΠΏΡ€ΠΈΡ‡ΠΈΠ½ младСнчСской смСртности, Π²Ρ‹Π·Π²Π°Π½Π½ΠΎΠΉ наслСдствСнными заболСваниями.

    Spinal muscular atrophy (SMA) is a neuromuscular disease caused by deletion or mutation in SMN1 gene. SMA human induced pluripotent stem cells (iPSCs) represent a useful and valid model for the study of the disorder, as they provide in vitro the target cells. We generated iPSCs from a SMA type I patient and SMA type II patient by using non-integrating episomal plasmid vectors. The resulting iPSCs are episomal-free, express pluripotency markers, display a normal karyotype, retain the mutation (homozygous deletion of SMN1) and are able to differentiate into the three germ layers
