Muscular Dystrophies (MDs) are a group of inherited diseases and heterogeneous in nature. To date, 40 different genes have been reported for the occurrence and/or progression of MDs. This study was conducted to demonstrate the application of next-generation sequencing (NGS) in developing a time-saving and cost-effective diagnostic method to detect single nucleotide variants (SNVs) and copy number variants (CNVs) in a single test. A total of 123 cases clinically suspected of MD were enrolled in this study. Amplicon panel-based diagnosis was carried out for 102 (DMD/BMD) cases and the results were further screened using multiplex ligation-dependent probe amplification (MLPA). Whilst in the case of LGMD (N = 19) and UMD (N = 2), only NGS panel-based analysis was carried out. We identified the large deletions in 74.50% (76/102) of the cases screened with query DMD or BMD. Further, the large deletion in gene (N = 3) and known SNV mutations (N = 4) were identified in LGMD patients. Together, the total diagnosis rate for this amplicon panel was 70.73% (87/123) which demonstrated the utility of panel-based diagnosis for high throughput, affordable, and time-saving diagnostic strategy. Collectively, present study demonstrates that the panel based NGS sequencing could be superior over to MLPA.

Purpose: This study was undertaken to know the epidemiology of various microorganisms causing gastroenteritis in paediatric age group, to evaluate clinico-microbiological correlation with respect to the type of microorganism, to study the clinical presentations and impact of syndromic based film array assay on antimicrobial stewardship and patient management.
Methods: This is five years retrospective study in which the results of Gastrointestinal film array panel of stool specimens of children <=16 Years of age who presented with gastroenteritis during 2019 to 2023 were noted. Clinical correlation of the microbes was done with respect to suspected clinical diagnosis, age, immune status and other underlying illness.

: Genetic testing is important for diagnosing inherited retinal diseases (IRDs), but further evidence is needed on the utility of singleton genetic testing in an Australian cohort. : A consecutive series of individuals with clinically diagnosed IRDs without prior genetic testing underwent commercial panel-based sequencing (Invitae or Blueprint Genetics), clinical assessment, and multimodal imaging. Retinal images were graded using the Human Phenotype Ontology terms.

TFE3 and TFEB break-apart fluorescent in situ hybridization (FISH) assays are the gold standard for diagnostic confirmation of MiTF family altered renal cell carcinoma (MiTF RCC), which includes TFE3 rearranged RCC, and TFEB altered RCC. However, FISH assays for multiple reasons may lead to equivocal or false-negative results, especially in cryptic fusions resulting from intrachromosomal inversions involving 5' partner genes such as NONO, GRIPAP1, RBMX, and RBM10. When FISH results are negative in cases with strong morphologic suspicion of the listed tumor entities, pathologists may recommend targeted RT-PCR or panel-based RNA fusion sequencing for diagnostic confirmation.

DNA methylation biomarker assay based on cell-free DNA (cfDNA) is a promising method for early detection of lung cancer. In this study, we aimed to develop a prediction model based on cfDNA methylation biomarkers and cfDNA concentration for early detection of lung cancer.

Diagnosing Alport syndrome can be particularly challenging when targeted sequencing methods, such as panel-based next-generation sequencing (NGS), fail to identify pathogenic variants, especially deep intronic mutations. The syndrome is caused by mutations in type IV collagen genes (, , or ), with X-linked Alport syndrome (XLAS) accounting for approximately 80% of cases. Here, we report the case of a 4-year-old boy who presented with persistent microscopic hematuria detected during routine urinalysis.
