Noonan Syndrome (NS)
Individuals afflicted with Noonan syndrome (NS) often exhibit distinct facial features, short stature, cardiac abnormalities, coagulation issues, skeletal deformities, and other associated symptoms. Our company is dedicated to advancing research and innovation in the field of rare diseases that can help you move from NS therapy development to therapy commercialization.
Introduction to Noonan Syndrome (NS)
Noonan syndrome (NS) is a complex genetic disorder characterized by a wide array of physical manifestations impacting various systems within the body. The estimated incidence of NS ranges from 1:1000 to 1:2500. The pathogenesis of NS revolves around disruptions in the RAS/MAPK signaling pathway, a crucial mechanism responsible for regulating cell division, growth, differentiation, and migration. Genes such as PTPN11, SOS1, RAF1, and RIT1 play pivotal roles in this signaling cascade, and mutations in these genes commonly lead to the development of NS. These mutations often result in prolonged activation of the proteins encoded by these genes, causing dysregulation in the RAS/MAPK pathway.

The diagnosis of NS is primarily established through molecular genetic testing, specifically identifying heterozygous or biallelic pathogenic variants in genes associated with NS, such as PTPN11 or LZTR1. In cases where the phenotype strongly suggests NS, a multigene panel test is often used to pinpoint the genetic cause effectively, minimizing the identification of variants of uncertain significance. Approximately 50% of individuals with NS carry a pathogenic missense variant in the PTPN11 gene. If the diagnosis remains uncertain after initial testing, more advanced genomic approaches, such as exome sequencing, may be employed to identify additional genetic factors contributing to the disorder.
Therapeutics Development of NS
While there is no cure for NS, ongoing research into potential therapeutics aims to address specific symptoms and complications associated with the condition. The MEK inhibitor trametinib has shown promise in treating infants with NS-related heart conditions, leading to the reversal of myocardial hypertrophy and improved somatic growth. Additionally, the use of trametinib in individuals with SOS1-related NS demonstrated positive outcomes in resolving lymphangiectasia and chylothorax.
