Article Synopsis
  • The ChiCaP study investigates the role of childhood cancer predisposition (ChiCaP) syndromes and how integrating germline whole-genome sequencing (gWGS) with tumor sequencing can improve diagnosis and treatment strategies for children with solid tumors.
  • Out of 309 children tested, 11% were diagnosed with ChiCaP syndromes, often missed before, showing significant diagnostic yield especially in certain cancers like retinoblastomas and high-grade astrocytomas.
  • The findings underscore the importance of combining systematic phenotyping and genomic diagnostics, as it enables personalized care and tailored treatment recommendations for a substantial number of affected patients.

Article Synopsis
  • The study examined how whole-genome sequencing (WGS) and RNA sequencing can help in diagnosing and treating childhood cancers, focusing on children with primary or relapsed solid tumors in Sweden.
  • Over the first 14 months, 118 tumors were analyzed, and 95% of those with mutations had clear clinical relevance, with significant findings such as additional subclassifications and potential treatment targets in 26% of the cases.
  • Overall, the research highlights the importance of integrating genomic data into clinical decision-making for improved diagnosis and treatment options in pediatric solid tumors.

Objectives: The aim of this study was to investigate genetic outcomes, analyze the family experience, and describe the process of implementing genetic sequencing for children with profound sensorineural hearing loss (SNHL) at a tertial audiological center in southern Sweden.

Design: This is a prospective pilot study including eleven children with profound bilateral SNHL who underwent cochlear implant surgery. Genetic diagnostic investigation was performed with whole exome sequencing (WES) complemented with XON-array to identify copy number variants, using a manually curated gene panel incorporating 179 genes associated with non-syndromic and syndromic SNHL.

Objective: To describe a possible novel genetic mechanism for cerebral small vessel disease (cSVD) and stroke.

Methods: We studied a Swedish kindred with ischemic stroke and intracerebral hemorrhage, tremor, dysautonomia, and mild cognitive decline. Members were examined clinically, radiologically, and by histopathology.

Backgrounds and Purpose- Although new methods for genetic analyses are rapidly evolving, there are currently knowledge gaps in how to detect Mendelian forms of stroke. Methods- We performed whole-exome sequencing in 22 probands, under 56 years at their first ischemic stroke episode, from multi-incident stroke families. With the use of a comprehensive stroke-gene panel, we searched for variants in stroke-related genes.

Mosaic genome-wide paternal uniparental disomy (GW-pUPD) is a rarely recognised disorder. The phenotypic manifestations of multilocus imprinting defects (MLIDs) remain unclear. We report of an apparently non-syndromic infant with severe congenital hyperinsulinism (CHI) and diffuse pancreatic labelling by 18F*-DOPA-PET/CT leading to near-total pancreatectomy.

Extensive analyses of known monogenic causes of stroke by whole-exome/genome sequencing are technically possible today. We here aimed to compile a comprehensive panel of genes associated with monogenic causes of stroke for use in clinical and research situations. We systematically searched the publically available database Online Mendelian Inheritance in Man, and validated the entries against original peer-reviewed publications in PubMed.
