Motivation: Rare diseases remain difficult to diagnose due to limited patient data and genetic diversity, with many cases remaining undiagnosed despite advances in variant prioritization tools. While large language models have shown promise in medical applications, their optimal application for trustworthy and accurate gene prioritization downstream of modern prioritization tools has not been systematically evaluated.

Results: We benchmarked various language models for gene prioritization using multi-agent and Human Phenotype Ontology classification approaches to categorize patient cases by phenotype-based solvability levels. To address language model limitations in ranking large gene sets, we implemented a divide-and-conquer strategy with mini-batching and token limiting …

Rationale: Atherosclerotic cardiovascular disease (ASCVD) represents the predominant cause of mortality and morbidity globally. Given the established role of hypercholesterolemia as a significant risk factor for ASCVD, the discovery of new lipid-lowering medications is of paramount importance. ATP citrate lyase (ACLY) is a crucial enzyme in cellular metabolism, providing acetyl-CoA as the building block for the biosynthesis of fatty acids and cholesterol. Consequently, it has emerged as a promising drug target for innovative treatments of lipid metabolic disorders.

Methods: Virtual screening of a natural product library was performed to identify small-molecule ACLY inhibitors, leading to the discovery of isoginkgetin (ISOGK). …

Intraocular Lens Power Calculation In Challenging Cases, Jack X Ma, Li Wang, Douglas D Koch

Faculty, Staff and Students Publications

In this article, we reviewed recently published papers of intraocular lens (IOL) power calculation in special eyes. In short eyes, accurate estimation of effective lens position is critical, and the ZEISS artificial intelligence IOL calculator produces the best outcomes. In long eyes, accuracy has been improved with axial length (AL) adjusted formulas such as the Wang-Koch AL adjustment and newer IOL formulas. In keratoconic eyes, hyperopic refractive outcomes increase with steeper keratometric values, and accuracy is poor in eyes with keratometric values ≥50.0 D. Two keratoconus-specific formulas (Barrett True K for keratoconus and Kane keratoconus) have been introduced. In eyes …

Genetic Newborn Screening For Retinoblastoma: A Belgian Initiative Baby Detect, Daniel A Rodriguez, Alex Song, Anshul Bhatnagar, Christina Y Weng

Faculty, Staff and Students Publications

Baby Detect Project, started in September 2022, aimed to create a newborn screening test using targeted next-generation sequencing for all early-onset, treatable, and serious conditions. The elaborated gene panel covers 405 genes, associated with 165 genetic conditions, and includes RB1, linked to retinoblastoma, the only oncological disease tested for. Germline RB1 mutations concern around 50% of all retinoblastoma cases and 100% of the most severe, bilateral cases. Ninety percent of them occur de novo, which delays the diagnosis by about a year with subsequent loss of vision and sometimes the eye itself. Detecting children with germline RB1 mutation at …

Examining Parents’ Perceptions Of Their Children’S Autism And Completion Of Genetic Testing, Georgina J Sakyi, Sarah S Mire, Robin P Goin-Kochel, Chaya N Murali, Susan X Day

Faculty, Staff and Students Publications

Though genetic testing is recommended for children diagnosed with autism spectrum disorder (ASD), both internal (e.g. parents’ and providers’ valuation of genetic testing) and external (e.g. insurance coverage) barriers exist, and exploration of these factors is required to close the gap between provider recommendations and parent follow-through. In a sample of 290 parents, we explored (a) how parents’ ASD-related etiological beliefs and symptom attributions, as well as income, affected genetic testing completion; and (b) whether these factors influence parents’ hopes or concerns about genetic testing. Principal component analysis (PCA) was used to investigate the factor structure of the ASD attribution …

Despite the efficacy of approved severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in preventing severe disease and death, breakthrough infections continue to occur in vaccinated individuals, contributing to further viral mutation and spread. These limitations may be attributable to the poor induction of mucosal immunity by parenteral vaccination. Mucosal adjuvants, such as T-vant, can enhance vaccine-induced immune responses through the generation of antigen-specific antibodies and T cells in the respiratory tract. In this study, we evaluated the protective efficacy of adjuvanted SARS-CoV-2 receptor binding domain (RBD) subunit vaccines administered by homologous and heterologous routes. Immunized mice were challenged with …

Zero-Inflated Models For The Evaluation Of Colorectal Polyps In Colon Cancer Screening Studies-A Value-Based Biostatistics Practice, Alok K Dwivedi, Sherif E Elhanafi, Mohamed O Othman, Marc J Zuckerman

Faculty, Staff and Students Publications

Background: Colon cancer screening studies are needed for the early detection of colorectal polyps to reduce the risk of colorectal cancer. Unfortunately, the data generated on colon polyps are typically analyzed in their dichotomized form and sometimes with standard count models, which leads to potentially inaccurate findings in research studies. A more appropriate approach for evaluating colon polyps is zero-inflated models, considering undetected existing polyps at colonoscopy screening.

Method: We demonstrated the application of the zero-inflated and hurdle models including zero-inflated Poisson (ZIP), zero-inflated robust Poisson (ZIRP), zero-inflated negative binomial (ZINB), zero-inflated generalized Poisson (ZIGP), zero hurdle Poisson (ZHP), and …
