Reymundo  Lozano

Clinical Interests

Dr. Lozano is a Pediatric Geneticist, who has dedicated his research to better understanding the molecular basis of genetic disorders associated with intellectual disabilities and autism spectrum disorders (ASD).

He is an International Medical Graduate from Mexico and completed his subspecialty studies at UCLA. He specializes in the treatment of neurodevelopmental genetic syndromes including fragile X syndrome (FXS), Angelman syndrome, 15q duplication syndrome, 22q11 microdeletion syndrome, and Noonan syndrome and other RASopathies.

His work focuses on different clinical trials for ASD and FXS. Dr. Lozano is dedicated to finding better treatments and eventually the cure for neurodevelopmental disorders.

He is also studying the phenotypic variability of fragile X premutation carries and the additive effects of other “genetic hits” and environmental exposures.

He pursues the genetic diagnosis of ASD, using cutting edge technology, including microarrays, mitochondrial function and whole exome sequencing.   

Dr. Lozano is an advocate for minority participation in clinical trials and his goal is to provide the necessary information to enhance enrollment and retention of minority participants.

He is involved in identifying the linguistic and systemic barriers to early diagnosis and intervention commonly found in Hispanic children with ID and ASD.

He is also interested in increasing diversity among medical students and faculty members at UC Davis.
