This is cool! The link from Plexin/Semaphorin to R-RAS signaling raises interesting questions about mechanism of action underlying clinical manifestations of human germline gain of function variants in #Noonansyndrome. (🔼bleeding, 🔼lymphatic dysplasia, CNS 🔼oligod 🔼myelination, muscle hypotonia)
For today's #FluorescenceFriday I'm thrilled to share that
ScienceAdvances was so nice to pick my picture as this week's featured image!

"I wish more was known about why growth hormone seems to help some kids' pain."
#RASopathies are short stature syndromes and GH is approved for #Noonansyndrome. It helps with pain, weakness, stamina, and growth. Any good science / med reviews on why? 🧪💪🦴

February is #Noonansyndrome awareness month AND the month when we recognize #RareDisease Day (Feb 28). We advocate for research and therapeutic progress 💊 for conditions caused by #RAS#MAPK signaling dysfunction. BTW, its not so rare. NS is ~1:2000 people!
