Anna Ryabets-Lienhard

Anna Ryabets-Lienhard, DO, is an Assistant Professor of Clinical Pediatrics at the University of Southern California, affiliated with Children's Hospital Los Angeles (CHLA). Her clinical and research focus centers on pediatric endocrinology, with particular expertise in genetic disorders, metabolic syndromes, and rare pediatric conditions. She actively contributes to translational and clinical studies addressing skeletal abnormalities, hormonal dysregulation, and pharmacotherapeutic strategies for complex pediatric cases.

Dr. Ryabets-Lienhard's research interests span genetic mutations affecting bone metabolism (e.g., GNAS, FAM111B), metabolic complications in Duchenne muscular dystrophy, and endocrine manifestations of syndromic disorders like congenital adrenal hyperplasia. Her work emphasizes improving clinical outcomes through biomarker identification and guideline development for therapies such as Teplizumab.

Her publications reflect a multidisciplinary approach, integrating genetics, endocrinology, and clinical care. Notable contributions include studies on pseudohypoparathyroidism epigenetics, RANKL/OPG ratios in muscular dystrophies, and carotid intima-media thickness in congenital adrenal hyperplasia patients. She regularly participates in national meetings, including the Pediatric Endocrine Society and Endocrine Society conferences, to disseminate findings and shape clinical practice.

Dr. Ryabets-Lienhard’s clinical expertise includes managing complex cases such as optic nerve hypoplasia, progressive osseous heteroplasia, and syndromic skeletal disorders. She collaborates with CHLA and USC teams to advance care for pediatric patients with rare and multifaceted endocrine conditions.
