Fragile X Spectrum Disorder Clinic

The Fragile X Spectrum Disorder Clinic at the Icahn School of Medicine at Mount Sinai, hosted by the Division of Medical Genetics, provides comprehensive medical evaluations and treatments to patients and families affected by Fragile X Syndrome (FXS) - the most common inherited cause of intellectual disability and autism - and its associated disorders.

We provide the following services:

  • Medical Evaluation
  • Genetic Counseling
  • Behavioral and Psychological Consultation

Led by renowned Fragile X researcher Reymundo Lozano, MD, our team of doctors, genetic counselors, and psychologists, aim to provide services created to meet the needs of patients with FXS. We also treat patients with related disorders such as permutation related disorders – Fragile X-associated Tremor/Ataxia Syndrome (FXTAS), Fragile X-associated Primary Ovarian Insufficiency (FXPOI) – and their families, by using the latest technological resources available.

We are a prominent member of the Fragile X Clinical and Research Consortium (FXCRC), a group of select, independent yet collaborative clinics supported by the National Fragile X Foundation, that works toward the common goal of managing patient symptoms, as there is currently no cure. Our program also provides opportunities to participate in pioneering research studies.
