Overview
The Fragile X Laboratory provides molecular analysis of the fragile X gene FMR1 by PCR and Southern analysis in conjunction with IBR’s Specialty Clinical Laboratories. We have performed more than 3,000 fragile X prenatal studies of chorionic villi (CVS) and amniotic fluid (AF). We also provide diagnostic laboratory services for women screened for fragile X carrier status and for individuals with developmental disabilities.
Fragile X syndrome is a common cause of an inherited developmental disability caused by the expansion of a CGG repeat in the 5’ untranslated region of the FMR1 gene. While the repeat is stable in the general population, the repeat size increases dramatically in families with Fragile X syndrome. Our research is targeted at identifying factors that contribute to repeat instability within families.
