Context: Previously, reduced levels of anti-Müllerian hormone (AMH), a circulating marker of ovarian reserve, were found in females with Fanconi anemia (FA). FA, dyskeratosis congenita (DC), and Diamond-Blackfan anemia (DBA) are inherited bone marrow failure syndromes (IBMFS) associated with high risks of bone marrow failure, leukemia, and solid tumors. Objective: The objective of the study was to assess AMH levels in females with DC or DBA. Design and Setting: This observational study used the National Cancer Institute's inherited bone marrow failure syndrome cohort at the National Institutes of Health Clinical Center. Participants: The study included females with DC, unaffected female relatives of patients with DC, females with DBA, unaffected female relatives of patients with DBA, and unrelated healthy female volunteers younger than 41 years of age. Main Outcome measure: Serum AMH levels were measured. Results: Females with DC had significantly lower levels of AMH (median 0.55 ng/mL) compared with unaffected relatives (median 2.28 ng/mL, P = .004) or unrelated healthy volunteers (median 2.69 ng/mL, P= .005). Females with DBAshoweda nonsignificanttrend for lower levels of AMH (median 0.89 ng/mL) compared with unaffected relatives (median 1.71 ng/mL, P = .21) or unrelated healthy volunteers (P = .11). Patients with DC and DBA had significantly higher levels of AMH (P = .013, P = .003) compared with FA (median 0.05 ng/mL). Conclusions: Our findings suggest that women with IBMFS have lower levels of AMH than unaffected women. This AMH deficiency could be a primary ovarian defect or a consequence of the pathophysiology of the syndromes. Additional studies of AMH and ovarian function in women with IBMFS are warranted to better understand the underlying biology.
