Back in 1900 the life expectancy of people with Down Syndrome was 9 years. In 1984, it was 28 years, today it's leveled off ...

Decades ago, researchers showed that Down syndrome (also known as trisomy 21), was caused when individuals carried an extra copy of chromosome 21. Down syndrome is also the most common genetic cause ...

Chromosome 21 was the second human chromosome to be fully sequenced. Down syndrome happens when Trisomy 21 occurs, which means that each cell is the body has three copies of chromosome 21 instead ...

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the ...

“It’s not just about fixing one gene,” explains Dr Oyieke. “Down Syndrome affects 326 genes on chromosome 21—editing that entire package is a monumental challenge.” Ethical concerns ...
