Support heterosexuality found using various methods: sexual orientation perceptions a target who engaged in incongruent beha...

Certain chromosomal regions called common fragile sites are prone to difficulty during replication. Many tumors have been shown to contain alterations at fragile sites. Several models have been proposed to explain why these sites are unstable. Here we describe work to investigate models of fragile site instability using a yeast artificial chromosome carrying human DNA from a common fragile site...

Fragile X syndrome is now a well established common clinical entity and most of those who are aware of the condition probably know that it takes its name from a rare fragile site (FRAXA) on the X chromosome. This is the best known fragile site and its clinical significance is clear. Similar, but a little less known is FRAXE, a fragile site close to that associated with fragile X syndrome, but i...

The present study explored the behavioral profile of individuals with fragile X syndrome during adolescence and adulthood. Individuals with both fragile X syndrome and autism (n  =  30) were compared with (a) individuals diagnosed with fragile X syndrome (but not autism; n  =  106) and (b) individuals diagnosed with autism (but not fragile X syndrome; n  =  135) on measures of autism symptoms, ...
