Purpose: Little is known about sex-specific manifestations of tuberous sclerosis complex. Inactivating mutations in the TSC1 and TSC2 genes cause tuberous sclerosis complex, and recent evidence points to a crucial role for these genes in maintaining appropriate ovarian function. The main objective of this study was to estimate reproductive dysfunction in a sample of women with tuberous sclerosis complex.
Methods: We designed a three-part questionnaire that included demographic information, reproductive history, and tuberous sclerosis complex history, and developed strict criteria to assess patterns in menstrual cyclicity; we analyzed 182 responses from female adult members of the Tuberous Sclerosis Alliance.
Results: More than one-third of women in our sample displayed some degree of menstrual irregularity, and their reported miscarriage rate was 41%. More than 4% of women had reproductive histories suggestive of premature ovarian insufficiency, higher than the general population estimate of 1%.
Conclusion: Our data reveal an underappreciated aspect of tuberous sclerosis complex in affected women, suggesting that a further exploration of the role the tuberous sclerosis complex genes play in reproductive function is warranted.
