Summary: The genetic architecture of complex traits can be influenced by both many common regulatory variants with small effect sizes and rare deleterious variants in coding regions with larger effect sizes. However, the two kinds of genetic contributions are typically analyzed independently. Here, we present GenRisk, a python package for the computation and the integration of gene scores based on the burden of rare deleterious variants and common-variants-based polygenic risk scores. The derived scores can be analyzed within GenRisk to perform association tests or to derive phenotype prediction models by testing multiple classification and regression approaches. GenRisk is compatible with VCF input file formats.
Availability And Implementation: GenRisk is an open source publicly available python package that can be downloaded or installed from Github (https://github.com/AldisiRana/GenRisk).
Supplementary Information: Supplementary data are available at Bioinformatics online.

Fetal brain anomalies identified by prenatal ultrasound and/or magnetic resonance imaging represent a considerable healthcare burden with ∼1-2/1,000 live births. To identify the underlying etiology, trio prenatal exome sequencing or genome sequencing (ES/GS) has emerged as a comprehensive diagnostic paradigm with a reported diagnostic rate up to ∼32%. Here, we report five unrelated families with six affected individuals that presented neuroanatomical, craniofacial, and skeletal anomalies, all harboring rare, bi-allelic deleterious variants in SNAPIN, which encodes SNARE-associated protein.

Background: Among childhood cancer survivors, germline rare variants in autosomal dominant cancer susceptibility genes (AD CSGs) could increase subsequent neoplasm (SNs) risks, but risks for rarer SNs and by age at onset are not well understood.
Methods: We pooled the Childhood Cancer Survivor Study and St Jude Lifetime Cohort (median follow-up = 29.7 years, range 7.

Introduction Stereotactic radiosurgery (SRS) is widely regarded as the standard of care after the resection of brain metastases in order to reduce local cavity recurrence risk. The objective of this study was to explore the reproducibility of published outcomes for patients receiving post-operative stereotactic radiosurgery (cavity SRS) in a National Health Service (NHS) setting for a non-selective series of patients. For our service, the median interval between surgery to cavity SRS (cSRS) is eight weeks, whereas similar timelines have been found to have a deleterious impact on survival in the published literature.

Accurate variant calling is essential for next-generation sequencing (NGS)-based diagnosis of rare diseases, yet most benchmarking studies have focused on standard cell lines or trio-based samples, with limited relevance to sporadic cases. Here, we systematically compared the performance of DeepVariant and GATK HaplotypeCaller in two Chinese cohorts of patients with sporadic epilepsy (EP) and autism spectrum disorder (ASD). DeepVariant exhibited higher precision and sensitivity in detecting single nucleotide variants (SNVs), while GATK showed a distinct advantage in identifying rare variants, which are often key to understanding the genetic basis of rare diseases.

Wiedemann-Rautenstrauch syndrome (WRS) is a rare neonatal progeroid disorder primarily associated with pathogenic variants in POLR3A. However, the pathogenicity of certain variants remains unclear. Here, we report a WRS case carrying the POLR3A c.
