👤 whose
Whose work first identified the fragile X syndrome?
Human BiologyGenetics
Quick Answer
J. P. Martin and colleagues first described the fragile site on the X chromosome, and later research linked it to the FMR1 gene. Fragile X is now recognized as a common inherited cause of intellectual disability.
The Full Story
Fragile X syndrome was first connected to a visible fragile site on the X chromosome in the late 1960s and early 1970s. Later molecular work identified the FMR1 gene and the CGG repeat expansion responsible for the disorder. The syndrome is associated with intellectual disability, learning differences, and autism-spectrum features in some individuals. It became a landmark example of how DNA repeat expansion can cause disease.
Key Facts
1.Fragile X is linked to the FMR1 gene
2.The disorder involves CGG repeat expansion
3.It is a leading inherited cause of intellectual disability
