Months after becoming the first infant to undergo gene-editing therapy for his rare genetic disorder, baby KJ has reached another milestone: taking his first steps.
Just one month after sharing her diagnosis publicly, Tatiana Schlossberg has passed away.
According to several reports, Schlossberg, who was the granddaughter of President John F. Kennedy, was diagnosed with acute myeloid leukemia in May 2024.
As WHDH 7 News reports, Schlossberg was diagnosed with the form of cancer after giving birth to her second child.
She was 35 years old at the time of her death on December 30.

In the essay she wrote revealing her diagnosis, Schlossberg, who is the daughter of Caroline Kennedy, said she didn’t know she was sick.
“I did not—could not—believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew. I regularly ran five to ten miles in Central Park. I once swam three miles across the Hudson River—eerily, to raise money for the Leukemia and Lymphoma Society. ” she wrote back in November.
“I had a son whom I loved more than anything and a newborn I needed to take care of. This could not possibly be my life.”
“When you are dying, at least in my limited experience, you start remembering everything,” the 35-year-old mom also added in The New Yorker piece she wrote. “Images come in flashes—people and places and stray conversations—and refuse to stop. I see my best friend from elementary school as we make a mud pie in her back yard, top it with candles and a tiny American flag, and watch, in panic, as the flag catches fire. I see my college boyfriend, wearing boat shoes a few days after a record-breaking snowstorm, slipping and falling into a slush puddle. I want to break up with him, so I laugh until I can’t breathe.”
“Maybe my brain is replaying my life now because I have a terminal diagnosis, and all these memories will be lost. Maybe it’s because I don’t have much time to make new ones, and some part of me is sifting through the sands.”
