Genotype-Phenotype Correlations in Chinese Pediatric Patients With Single Large-Scale Mitochondrial DNA Deletion Disorders.

Clinical genetics2026 Apr

This study investigated clinical and genetic characteristics of Chinese pediatric patients with single large-scale mitochondrial DNA deletions (SLSMD). We analyzed 28 patients (July 2004-March 2025) using long-range PCR and next-generation sequencing. Spearman correlation and ANOVA assessed genotype-phenotype relationships. Patients (mean age 5.52 ± 3.96 years) exhibited multi-organ involvement (5.43 ± 1.87 organs). Common initial presentations included ocular (29%), neurologic, and endocrine dysfunction. Only 14.3% had the classic 4977 bp deletion, and 23 novel deletions were identified in 25 patients. Larger deletions correlated with more deleted MRC complexes (r = 0.516, p = 0.0123) and more deleted tRNAs (r = 0.534, p = 0.0103). Kearns-Sayre syndrome (KSS) patients had later onset (p = 0.0337), larger deletions (p = 0.0263), and greater tRNA/MRC complex (p = 0.0263, p = 0.0319) involvement than non-KSS patients. SLSMD in Chinese children primarily causes KSS, Pearson syndrome (PS), and progressive ophthalmoplegia with multi-organ involvement. Genotype-phenotype correlations exist, particularly between deletion size, onset age, and disease severity. KSS patients show distinct genetic and clinical profiles, suggesting slower progression. This study expands the known SLSMD spectrum and underscores mitochondrial testing in pediatric multi-organ disorders.

Outcomes of kidney transplantation in three patients with single large-scale mitochondrial DNA deletion syndromes.

Molecular genetics and metabolism2026 Mar

Single large-scale mitochondrial DNA deletion syndromes (SLSMDS) are a clinical continuum of three classic discrete clinical syndromes: Pearson marrow-pancreas syndrome, Kearns-Sayre syndrome, and chronic progressive ophthalmoplegia. Kidney manifestations, including chronic kidney disease with progression kidney failure has emerged as significant cause of morbidity and mortality in SLSMDS. Despite this recognition, reports of kidney transplantation in this population are limited. Here, we describe outcomes of kidney transplantation in three patients with SLSMDS and kidney failure over a 1-2.5-year follow-up period. All three patients had multisystem involvement at the time of transplantation. In all three patients, surgery was uncomplicated without evidence of acute metabolic decompensation in the perioperative period and standard immunosuppressive protocols were well tolerated. One patient developed post-transplant lymphoproliferative disease at 9 months status-post transplant which was ultimately fatal. The two surviving patients remain with stable graft function and functional quality of life at 1- and 3.5-years post-transplant.

CRISPR prime editing of mitochondrial heteroplasmy in rare Kearns-Sayre syndrome: ocular and cardiac synergies.

Annals of medicine and surgery (2012)2026 Jan

Kearns-Sayre syndrome (KSS) is a rare mitochondrial disorder defined by a combination of ophthalmoplegia, pigmentary retinopathy, and cardiac conduction defects. KSS arises from mitochondrial DNA (mtDNA) deletions and heteroplasmic imbalance, where there is a variation in levels of normal versus abnormal mtDNA. Current therapies offer symptomatic relief at most; they do not address the primary issue of correcting the genetic mutation. Innovative methods employing CRISPR Prime Editing (PE), an accurate and RNA-less technology, allow for unique correction of pathogenic mtDNA variants and errors. By fixing the wild type to variant ratio, PE could directly correct ocular- and cardiac-related signs and symptoms in KSS, in two tissue types that are entirely dependent on mitochondrial bioenergetics for their energy needs. Furthermore, the use of tissue-specific delivery methods, such as AAV2 vectors or cardiomyocyte promoters, would further enhance the targeting of the corrective approach to more specifically correct disease processes. This represents a completely innovative approach to genomic correction in the field of mitochondrial medicine, and there is important to translate this research to the clinic.

Choroidal neovascularization in a teenager with Kearns Sayre syndrome.

Ophthalmic genetics2026 Feb

Kearns Sayre syndrome (KSS) is a rare multisystem mitochondrial disorder. KSS primarily targets energy supply in cells through impaired oxidative metabolism and reduced ATP (Adenosine triphosphate) production. KSS is clinically characterized by a classic triad of chronic progressive external ophthalmoplegia, retinitis pigmentosa and cardiac conduction defect. Additional features may include neurological abnormalities, endocrinopathies, renal disease, growth failure, myopathy and more. We present a case of a young male with KSS, retinal dystrophy and multiple systemic abnormalities. Despite treatment with three intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, the CNV demonstrated limited response and progressive enlargement, leading to poor final visual outcome. To our knowledge, CNV has not been previously documented in Kearns -Sayre syndrome. This report underscores the need for ongoing surveillance in patients with rare retinal dystrophies, given the potential for unforeseen complications.

Mitochondrial tRNA-Derived Diseases.

International journal of molecular sciences2025 Dec 13

Mitochondrial tRNA genes are critical hotspots for pathogenic mutations and several mitochondrial diseases. They account for approximately 70-75% of disease-causing mtDNA variants despite comprising only 5-10% of the mitochondrial genome. These mutations interfere with mitochondrial translation and affect oxidative phosphorylation, resulting in remarkably heterogeneous multisystem disorders. Under this light, we systematically reviewed PubMed, Scopus, and MITOMAP databases through October 2025, indexing all clinically relevant pathogenic mt-tRNA mutations classified by affected organ systems and underlying molecular mechanisms. Approximately 500 distinct pathogenic variants were identified across all 22 mt-tRNA genes. Beyond typical syndromes like MELAS, MERRF, Leigh syndrome, and Kearns-Sayre syndrome that are linked to mt-tRNA mutations, they increasingly implicate cardiovascular diseases (cardiomyopathy, hypertension), neuromuscular disorders (myopathies, encephalopathies), sensory impairment (hearing loss, optic neuropathy), metabolic dysfunction (diabetes, polycystic ovary syndrome), renal disease, neuropsychiatric conditions, and cancer. Beyond sequence mutations, defects in post-transcriptional modification systems emerge as critical disease mechanisms affecting mt-tRNA function and stability. The mutations on tRNA genes described herein represent potential targets for emerging genome editing therapies, although several translational challenges remain. However, targeted correction of pathogenic mt-tRNA mutations holds transformative potential for precision intervention on mitochondrial diseases.
