Summary: Primary hyperoxaluria type 3 (PH3) is characterized by symptoms at a younger age compared to PH1 and PH2, with lower urine oxalate excretion and higher urine calcium levels. Stone events are similar across age groups and PH types, with a lower risk of kidney failure in PH3 patients compared to PH1 and PH2 by age 40. Long-term follow-up studies of larger cohorts are needed to further understand the PH3 phenotype.

Summary: Primary hyperoxaluria type 1 is a rare genetic disease caused by hepatic overproduction of oxalate, leading to kidney stones, nephrocalcinosis, kidney failure, and systemic oxalosis. This trial tested the efficacy of lumasiran, an RNAi therapeutic agent, in reducing hepatic oxalate production. The results showed that lumasiran significantly reduced urinary oxalate excretion, alleviating the cause of kidney failure in PH1 patients.

Summary: Primary hyperoxaluria (PH) is a genetic disorder that results in increased hepatic production of oxalate. PH type 3 (PH3) is the most recently identified subtype and can lead to kidney failure. Family history of the disease and marked hyperoxaluria can suggest the presence of PH3. Treatment options include hydration and medication.

Summary: This study aims to investigate the factors influencing stone formation in primary hyperoxaluria type 3 patients. The analysis of stone events and associations with urine parameters and kidney function showed that primary hyperoxaluria type 3 patients have a high prevalence of kidney stones, with increasing event rate and surgical intervention. Higher calcium oxalate supersaturation is associated with increased lifetime stone event rate.

Summary: Nedosiran, an investigational RNA interference agent, demonstrated significant reductions in urinary oxalate levels in participants with primary hyperoxaluria (PH), particularly in the PH1 subgroup. Nedosiran also showed a sustained reduction in plasma oxalate and was generally safe and well tolerated. These findings indicate the potential of nedosiran as a treatment option for PH.

Summary: Outcome data for primary hyperoxaluria type 3 (PH3), considered a milder form of PH with lower risk of chronic kidney disease, are scarce. A retrospective analysis of the largest PH3 cohort to date revealed that PH3 is more similar to PH1 and PH2 than previously thought, presenting as early-onset, recurrent stone disease with potential kidney impairment.

Summary: This study demonstrated the potential of the Cpf1 CRISPR system to simultaneously target multiple genes and alleviate the pathogenic phenotype in primary hyperoxaluria type I (PH1). Targeting the Hao1 and Ldha genes resulted in decreased oxalate levels and improved disease pathology in PH1 rats, providing a proof-of-concept for multiplex genome editing-based gene therapy.

Summary: The lack of targeted treatments in RAS mutant colorectal cancers leads to poorer prognosis compared to RAS wild-type disease. Liquid biopsy studies have shown that RAS mutant clones may disappear in plasma during clonal evolution, potentially enabling new possibilities for EGFR blockade. However, the detection of RAS mutations in plasma may be hindered by the low levels of circulating ctDNA, necessitating a more precise selection of true RAS mutation converters. In this study, evaluating RAS mutational status at the time of disease progression in initially RAS-mutant patients revealed a 37.5% incidence of true RAS converters, with a trend towards improved PFS in patients receiving anti-EGFR treatment as second or subsequent lines.

Summary: This study identified that certain candidate variants associated with dRTA can lead to exon skipping by disrupting ESEs, generating ESS, or interfering with classic splicing sites. It highlights the importance of assessing the effects of exonic variants at the mRNA level and suggests that minigene analysis is an effective tool for evaluating splicing effects.

Summary: The recurrent 2q13 deletion syndrome is a rare genetic disorder characterized by developmental delay, cardiac and urogenital malformations, and minor facial anomalies. Congenital heart defects are the most common malformations associated with this syndrome, with highly variable types observed, including partial anomalous pulmonary venous connection, muscular ventricular septal defect, and aortic valve insufficiency.

Summary: Liquid biopsies, specifically real-time polymerase chain reaction and next-generation sequencing, were compared to track the KRAS G12C mutation at disease progression onset. 24% of patients acquired the KRAS G12C mutation at the time of progressive disease, and all patients with this mutation in tissue samples became negative in circulating tumor DNA at progressive disease. Real-time PCR assay Idylla could be a suitable approach to match patients with interventional biomarker-targeted therapies based on the assessment of plasma KRAS G12C mutation as a druggable target.

Summary: Choroideremia is an X-linked recessive condition that primarily affects males, causing progressive visual loss due to degeneration of retinal and choroidal tissues. The disease is caused by alterations in the CHM gene, leading to dysfunction of the protein REP1, which is crucial for prenylation of Rab. While female carriers are usually unaffected, this study identified a novel CHM pathogenic variant in a family with affected females. The variant resulted in a shorter CHM isoform, impairing REP1/Rab binding and potentially explaining the complex manifestations of Choroideremia in females.

Summary: Due to the implementation of NGS technologies, the diagnostic yield of neurodevelopmental disorders has significantly increased. Transcription-related genes and chromatin remodeling genes are the most commonly implicated genes in these disorders. In this study, a 27-year-old female patient with moderate intellectual disability and other neuropsychiatric and behavioral issues was found to have a de novo heterozygous stop variant in the KDM5C gene. The findings contribute to the understanding of genotype-phenotype correlations and the characterization of a recognizable phenotype associated with KDM5C mutations.

Summary: Asperger syndrome is a pervasive developmental disorder characterized by impaired socialization, stereotypical behavior, and defective social adaptation. Genetic background is important in the development of Asperger syndrome, and a mutation in the RADX gene may play a role as a predisposing factor. The RADX gene encodes a DNA binding factor involved in genome maintenance and its mutation could disrupt neural genes related to cell adhesion and migration.
