Z-DNA Flipons & Disease: How AI is Revolutionizing Genomic Research

In a collaborative effort, the HSE University and Sber Artificial Intelligence Lab have harnessed the power of AI to pinpoint specific DNA sequences in the genome capable of converting into a unique mirror-like formation known as Z-DNA. Intriguingly, these DNA segments have been identified to overlap with mutations linked to significant inherited disorders, potentially influencing various physiological attributes such as height, weight, cholesterol levels, and even hair coloration. The groundbreaking findings have been showcased in the Life Science Alliance journal.

The Z-DNA conformation essentially mirrors the typical DNA configuration. Contrary to the widely recognized right-twisted double helix structure, Z-DNA assumes a left-twisted twist. There are particular DNA segments, termed ‘flipons’, that have the remarkable capability to transmute the customary DNA architecture into its reflection. Notably, beyond merely altering the structure, these flipons can influence how genomic data is interpreted.

The HSE International Laboratory of Bioinformatics joined forces with the Sber Artificial Intelligence Lab to delve deeper into the genomic placements of Z-DNA flipons, aiming to understand the implications of such inversions in human DNA.

Through a neural network model, that was previously trained using experimental datasets, the team managed to proficiently predict flipon locations across the genome. It was observed that these spots overlapped with genes associated with critical genetic ailments, emphasizing the transformative role of inverted DNA structures.

The study further shed light on the association between Z-DNA and a slew of hereditary disorders, such as osteogenesis imperfecta, Waardenburg syndrome, and hemoglobinopathy. Furthermore, mutations interacting with Z-flipon regions can significantly impact various human traits and bodily functions.

Elaborating on the significance of the study, Dmitry Umerenkov, Executive Director of Data Research at the Sber Artificial Intelligence Lab, noted, “While our experimental data pinpoints specific DNA areas showcasing alternative configurations during our testing phase, numerous potential sites could adopt varying structures. Our crafted algorithm traces all such potential configurations, equipping biologists with tools to probe deeper into the interplay between flipons and other genetic systems.”

Maria Poptsova, who leads the HSE International Laboratory of Bioinformatics, added, “This research marks pivotal progress in discerning the influence of alternative DNA shapes within our bodies. By mapping out Z-flipons, we’re setting the foundation for future hypothesis testing. This flipon atlas could prove instrumental in connecting mutations with distinct clinical scenarios, potentially unlocking innovative therapeutic avenues for grave illnesses.”
