One copy of the Christchurch variant may confer protection against familial Alzheimer's disease

A scientific story that began with a discovery in just one extraordinary patient is now panning out. In 2019, an international team that included researchers from two Mass General Brigham hospitals -; Mass Eye and Ear and Massachusetts General Hospital (MGH)-; reported on the case of a patient who did not develop cognitive impairment until her late 70s, despite being part of a family at extremely high genetic risk for developing early-onset Alzheimer's disease.

Mutated TREX1 gene linked to catastrophic DNA damage and deadly rare disease

TREX1 is a gene that is supposed to direct the maintenance of the entire body's DNA, but new research shows that when people are born with mutated TREX1, it causes catastrophic damage to the DNA over time, resulting in a deadly rare disease called retinal vasculopathy with cerebral leukoencephalopathy (RVCL).
