Now curated:
• SHOC2-MRAS-PP1 phosphatase complexes (RAF activation; linked to RASopathies incl. Noonan-like syndromes)
• KRAS/HRAS-SOS1 activation complexes
• KRAS-RAF1 & KRAS/MRAS-PIK3CA effector complexes

🌍 Rare Disease Day: When Molecular Complexes Break

Rare diseases aren’t just “gene disorders” - many disrupt macromolecular complexes, the molecular machines that keep cells running.

🔬 Dynein complex variants (e.g. DYNC1H1) impair axonal transport → Charcot-Marie-Tooth disease (CMT).

🔥 STING gain-of-function variants hyperactivate interferon signalling → SAVI.
