Hongyan Chai

Hongyan Chai is a Researcher at the Cytogenetics Laboratory within the Yale School of Medicine. Her work focuses on genomic and cytogenetic analysis of genetic disorders, particularly in the context of hepatocellular carcinoma, reproductive health, and prenatal diagnosis. She has contributed to studies on chromosomal abnormalities such as ring chromosomes, genetic risk factors in pregnancy loss, and molecular profiling of tumors. Her research integrates techniques like whole exome sequencing, array comparative genomic hybridization (aCGH), and meta-analysis to uncover diagnostic and prognostic markers. Collaborations involve interdisciplinary teams exploring oncogenic pathways, genetic etiologies of miscarriages, and cytogenomic diagnostics. Her publications span topics from genetic syndromes to biomarker discovery in liver cancer.

Key research areas include the molecular underpinnings of hepatocellular carcinoma, genetic mechanisms of pregnancy loss, and the clinical utility of cytogenomic assays in prenatal and pediatric settings. She has also investigated the role of non-coding RNAs and microRNAs in disease progression. Her work emphasizes translating genomic insights into clinical practice, such as improving diagnostic accuracy for congenital anomalies and cancer.
