Pluripotent cells, including embryonic stem (ES) and induced pluripotent stem (iPS) cells, are used to investigate the genetic and epigenetic underpinnings of human diseases such as Parkinson’s, Alzheimer’s, autism, and cancer. Mechanisms of somatic cell reprogramming to an embryonic pluripotent state are explored, utilizing patient-specific pluripotent cells to model and analyze neurodegenerative diseases.

The presentation will provide an overview of the expanding role of genetic factors in epilepsy. It will delve into the fundamentals of this field and elucidate how digital tools and resources can aid in the re-evaluation of genetic test results. In the initial segment of the presentation, Dr. Lal will examine the advancements made over the past two decades regarding the genetic architecture of various epilepsy types. Additionally, he will present research studies in which he has actively participated, offering concrete examples. Subsequently, during the second part of the talk, Dr. Lal will share the ongoing research projects that focus on epilepsy genetics, bioinformatics, and health record data science.

Due to high homology to the human genome and rapid development, zebrafish have been successfully used to model diseases of the neuromuscular system. In this seminar, I will present current advances in modeling genetic causes of Amyotrophic Lateral Sclerosis (ALS), the most common motor neuron degeneration and show how epistatic interaction studies in zebrafish have helped elucidate synergistic effects of major ALS genes and their cellular targets.

Whilst epilepsy may be a consequence of an acquired insult including trauma, stroke, and brain tumours, the genetic component to epilepsies has been greatly under-estimated. Considerable progress has recently occurred in the understanding of epilepsy genetics, both at a clinical genetic level and in the basic science of epilepsies. The clinical evidence for genetic components will be first briefly discussed including data from population studies, twin analyses and multiplex family studies. Initial molecular discoveries occurred via classical methods of linkage and gene identification. Recent large-scale hypothesis-free whole exome studies searching for rare variants and genome-wide association studies detecting common variants have been very rewarding. These discoveries have now impacted on clinical practice, especially in severe childhood epilepsies but increasingly so in adult patients. The “genetic background” of patients has long been posited as part of the reason that some patients have epilepsy, or perhaps why some have more severe epilepsy. This has been unmeasurable but now, with the development of polygenic risk scores, the “background” is now in the research foreground. The current and future impact of polygenic risk scores will be explored.
