PTPN11 : protein tyrosine phosphatase non-receptor type 11


The PTPN11 Gene: A Gatekeeper of Cell Function and Disease

Description:

The PTPN11 gene holds the blueprint for creating the SHP-2 protein, a crucial regulator in the RAS/MAPK signaling pathway. This pathway plays a pivotal role in cell growth, differentiation, migration, and apoptosis. During embryonic development, SHP-2 is essential for the formation of the heart, blood cells, bones, and other tissues.

Associated Diseases:

Mutations in the PTPN11 gene can lead to a spectrum of disorders, including:

  • Noonan syndrome: A genetic condition characterized by distinctive facial features, heart defects, and developmental delays.
  • Legius syndrome: A rare disorder involving multiple benign tumors, cognitive impairments, and distinctive facial features.
  • Juvenile myelomonocytic leukemia (JMML): A rare and aggressive form of childhood leukemia.

Did you Know ?

Approximately 1 in 20,000 individuals are affected by Noonan syndrome, making it one of the most common genetic syndromes associated with the PTPN11 gene.
