Genotyping vs. Sequencing: What's the Difference?

In this episode, Dr. William Stanford, Dr. Yelena Bykhovskaya and Taylor Cu discuss various genetic testing methods. The conversation compares genotyping, exome sequencing, and whole genome sequencing, with an emphasis on whole genome sequencing, which provides the most comprehensive genetic information.

Dr. William Stanford is co-founder of Biography Health. He began his career as a mechanical and aerospace engineer at Texas Instruments in 1982 while also pursuing his interest in aviation as a flight instructor and commercial pilot. In 1991, he pivoted into biomedical science and subsequently completed the combined M.D./Ph.D. physician-scientist training program at the University of California, Los Angeles, in 1998 and an internal medicine residency at UCLA in 2001. He is board-certified in internal medicine and is a Fellow of the American College of Physicians.

A pioneer in the field of hospital medicine, Dr. Stanford founded and led a 25-physician group of private practice hospitalists at Cedars-Sinai Medical Center in Los Angeles in 2002. After an extensive clinical career as the attending physician for over 100,000 patients, he was elected by his peers at Cedars-Sinai to be clinical chief of general internal medicine, serving in this capacity from 2017 to 2018. Inspired by recent advancements in biomedical science and medicine, Dr. Stanford completed professional certification through Stanford University’s Department of Genetics in 2018, further advancing his role as a true physician-scientist. Since 2018, he has provided genomic and precision medicine consultations through the Beverly Hills Institute for Precision Medicine

Dr. Yelena Bykhovskaya

Dr. Yelena Bykhovskaya is an accomplished scientist specializing in genetics and precision medicine. As the former Principal Scientist at Avellino Labs, she developed genetic tests for Mendelian and complex eye diseases using national and international collaborations. As the former Research Scientist at Cedars-Sinai, she made major advances in complex genetic eye diseases with groundbreaking genome-wide genetic analyses. Her earlier work in mitochondrial genetics led to major discoveries in maternally inherited deafness and other rare mitochondrial disorders. Holding a PhD in Biochemistry, Yelena has a publication record of widely cited forty-five articles in high-impact journals and delivered numerous oral and poster presentations at the national and international conferences, solidifying her leadership in genetic research.
