Abstract

Does an association exist between high normal numbers of CGG trinucleotide repeats on the fragile X mental retardation 1 (FMR1) gene and diminished ovarian reserve (DOR)? This large data set demonstrated that a high normal number of CGG repeats (35-54 repeats) on the FMR1 gene was not significantly correlated with DOR. The FMR1 premutation (55-200 repeats) is a known cause of primary ovarian insufficiency. However, the relationship between high normal CGG repeat numbers (35-54 repeats) and ovarian reserve has yet to be conclusively demonstrated. This is a retrospective data analysis conducted between January 2012 and February 2014 that included 1287 women. Over 1140 women had complete data. All women, excluding oocyte donors, who presented to a large private practice specializing in reproductive endocrinology and infertility for treatment and who underwent both fragile X and ovarian reserve testing were included. All fragile X testing was performed using triplet repeat PCR, with confirmation of positives by Southern blot. CGG repeat numbers from both alleles were recorded, and the allele with the higher number of repeats was used for statistical calculations. We did not differentiate between patients with one or two high normal...Continue Reading
