Advances in research on the mechanism of tsRNA action in tumours

At present, many studies have emphasized the importance of tsRNAs in tumors and revealed their important role in the biological processes of tumor cell proliferation, apoptosis, and metastasis. By systematically analyzing the production and biological function of tsRNAs in various tumors, we elucidate its mechanism of action in tumor occurrence and progression, and discuss their […]

A founder deletion involving BRCA1 in families of Nepalese origin: the perfect hiding place!

Deletions and duplications involving the BRCA1 gene can be found in a substantial proportion of families with inherited risk for breast and ovarian cancer. In this study, Pagnamenta et al identified two affected cousins from the 100,000 Genomes Project who shared a complex 178bp deletion in BRCA1. Due to its size and location, the deletion had escaped detection using multiple […]

Retrospective study on the utility of optical genome mapping as a follow-up method in genetic diagnostics

Genetic tests currently used in routine diagnostics are designed to detect almost all types of genetic aberrations that may cause disease. However, in some cases, aberrations can be detected, but remain partly unresolved: e.g., the detection of a large duplication often does not entail information on its point of insertion in the genome, which could […]

Aortic and Arterial Manifestations and Clinical Features in TGFB3-Related Heritable Thoracic Aortic Disease: Results from the Montalcino Aortic Consortium

This paper describes clinical features and aortic outcomes in patients with heritable thoracic aortic disease (HTAD) due to TGFB3 variants. Aortic dilation occurred in some but not all individuals, but aortic dissection (a tear in the aortic wall) occurred in very few patients and at older ages and at larger aortic diameters than in those […]

Unveiling non-coding DMD variants: synergising RNA sequencing and DNA sequencing for enhanced molecular diagnosis

By combining RNA sequencing with DNA analysis and immunohistochemistry , this study uncovered hidden pathogenic variants that traditional methods often miss for Duchenne and Becker muscular dystrophy (DMD/BMD) testing. Pan et al. identified splice-altering variants and complex DNA rearrangements in patients with unresolved DMD molecular diagnoses, enabling more precise detection of disease-causing changes. This innovative […]

Novel HYLS1 variants associated with Joubert syndrome suggest potential genotype-phenotype correlates

Joubert syndrome (JS) is a rare genetic ciliopathy, whose diagnostic hallmark is the “molar tooth sign” on brain MRI. Mutations in over 40 different genes can cause JS, many of which are involved in the proper functioning of primary cilia. HYLS1 gene is associated with a severe condition called Hydrolethalus syndrome, leading to early death. […]

From onset to blindness: a comprehensive analysis of RPGR-associated X-linked retinopathy in a large cohort in China

Mutations in the RPGR gene are the most common cause of X-linked retinopathy, a hereditary retinal disease. We have thoroughly characterized the clinical features and natural history of a large cohort of patients with RPGR-associated X-linked retinopathy, documenting the progression from onset to blindness. This detailed analysis provides valuable insights into the disease’s timeline, offering […]

Robust detection of pathogenic HYDIN variants that cause primary ciliary dyskinesia using RNA-seq of nasal mucosa

Primary ciliary dyskinesia (PCD) is a rare inherited condition that makes it hard for the body to clear germs from the lungs and nose, causing frequent infections. It is often confused with other illnesses, so genetic testing is important for a correct diagnosis. One tricky gene involved is HYDIN, as it has a nearly identical […]
