Martin Bell Syndrome.
Martin Bell Syndrome.
Fragile x syndrome was first described in 1943 by J.Purdon Martin and Julia Bell whose family had eleven members with fragile x symptoms although they did not know the cause or have a name for the condition at this time. In 1969, Fragile x was first discovered under the microscope by a scientist called Herbert Lubs who discovered that one of the arms of the X chromosome in people with fragile x was constricted which gave it the appearance of being broken which is how the name 'fragile x' came about. In 1991 Verkerk identified the cause for transcriptional silencing of the gene Fmr-1, that encodes the protein FMRP.
