Mutations That Cause SMA May Also Protect Against Infection, Hinting at Why They Continue to Thrive
Diminished levels of the survival of motor neuron (SMN) protein causes spinal muscular atrophy (SMA), and also disrupts a process called endocytosis — crucial for the transfer of nerve signals between cells. The findings, published in the journal PNAS in the study, “Decreased function of survival motor neuron…
