FMR1 genotypes and sub-genotypes have since been associated with different ovarian aging patterns [2,3], different pregnancy rates in association with in vitro fertilization (IVF) [3] but also with risk towards autoimmunity [3,8] and, likely, BRCA1/2 mutation-associated cancer risks [5], suggesting, yet additional, previously unknown biological functions for the FMR1 gene. This evidence concerns the gene FMR1 and Autoimmunity.
