Article Abstract
Background And Objective: The aim of this study was to clinically and molecularly characterize the largest cohort of patients with HK1 associated retinal disease. (HK1) variants have been reported to cause retinitis pigmentosa (RP), but a clearly defined genotype-phenotype correlation has not been well established.
Patients And Methods: A retrospective, consecutive, single-center case series was performed on patients with molecularly confirmed HK1-associated disease. Patients between 2016 and 2024 were included.
Results: Sixty eyes from 30 patients were assessed. Thirty patients of 22 unrelated families were included. The median age at presentation was 53.5 years old, and the median age of disease symptom onset was 36 years old. The p.Glu847Lys variant was exhibited by 97% of the patients. Median best-recorded visual acuity was 20/28. Pericentral RP was the predominant phenotype (90% of patients).
Conclusion: HK1 p.Glu847Lys variant was found to be associated with a less severe phenotype of autosomal dominant retinitis pigmentosa (adRP) as compared to other forms of adRP based on clinical presentation and electrophysiology. Future studies are necessary to better understand the genotypephenotype relationship and explore therapeutic options. .

LONP1 encodes a mitochondrial protease essential for protein quality control and metabolism. Variants in LONP1 are associated with a diverse and expanding spectrum of disorders, including Cerebral, Ocular, Dental, Auricular, and Skeletal anomalies syndrome (CODAS), congenital diaphragmatic hernia (CDH), and neurodevelopmental disorders (NDD), with some individuals exhibiting features of mitochondrial encephalopathy. We report 16 novel LONP1 variants identified in 16 individuals (11 with NDD, 5 with CDH), further expanding the clinical spectrum.

In the past century, the human Lifespan has doubled. However, this is not equivalent to Healthspan which refers to the number of years spent healthy and free from disease. Women have an additional level of complexity on the path to optimal healthspan where health resilience dramatically decreases following menopause and this is due to their ovaries aging by midlife.

Background: Variants of uncertain significance (VUS) represent a major diagnostic challenge in the interpretation of genetic testing results, particularly in the context of inborn errors of immunity such as severe combined immunodeficiency (SCID). The inconsistency among computational prediction tools often necessitates expensive and time-consuming wet-lab analyses.
Objective: This study aimed to develop disease-specific, multi-class machine learning models using in silico scores to classify SCID-associated genetic variants and improve the interpretation of VUS.

Whole blood (WB) transcriptomics offers a minimal-invasive method to assess patients' immune system. This study aimed to identify transcriptional patterns in WB associated with clinical outcomes in patients treated with immune checkpoint inhibitors (ICIs). We performed RNA-sequencing on pre-treatment WB samples from 145 patients with advanced cancer.

Vascular sites have distinct susceptibility to atherosclerosis and aneurysm, yet the epigenomic and transcriptomic underpinning of vascular site-specific disease risk is largely unknown. Here, we performed single-cell chromatin accessibility (scATACseq) and gene expression profiling (scRNAseq) of mouse vascular tissue from three vascular sites. Through interrogation of epigenomic enhancers and gene regulatory networks, we discovered key regulatory enhancers to not only be cell type, but vascular site-specific.
