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

Single large-scale mitochondrial DNA deletion syndromes: scientific and family conference optimizes the collection of rare disease research outcomes.
The SLSMDS Research Network is a collaborative network comprising patient advocates, researchers, clinicians, and affected families seeking to improve outcomes for individuals with single large-scale mitochondrial DNA deletion syndromes (SLSMDS). Building off of jointly developed research infrastructures, including a patient registry and natural history study, advocates and clinicians cohosted the SLSMDS Family and Scientific Conference, enabling the collection of patient data from an ultra-rare and geographically dispersed patient population. Here we describe the data collection procedures for single-time point laboratory assessments and patient reported outcomes for a subset of individuals with SLSMDS. Utilizing a reproducible model of rare disease data collection, we expand our understanding of the common psychiatric manifestations, describe variability in terms of self-care and quality of life, and emphasize potential biomarkers for individuals with SLSMDS. Our study describes how efficient patient-researcher partnerships can develop and sustain novel mechanisms to collect rare disease data, improve our understanding of the natural history of these disorders, and support development of future treatments.
Clinical and Morphological Bone Marrow Characteristics of Pearson Syndrome: About Three Consecutive Cases and Review of the Literature.
Pearson syndrome (PS) is a rare and fatal multisystem disorder caused by a mitochondrial DNA (mtDNA) deletion. Most patients develop refractory anemia in early infancy, rapidly followed by multiple complications such as failure to thrive, muscle hypotonia, pancreatic insufficiency, and renal tubulopathy. Although the definitive diagnosis is established by mtDNA sequencing, bone marrow (BM) cytology is a cornerstone of diagnosis, typically revealing precursor vacuolization and ring sideroblasts. We report here three cases of patients with PS encountered in our institution and summarize the clinical and hematological features of PS through a systematic review of the literature. The first symptoms mostly appear during the first month of life and rarely after 18 months. Hyporegenerative anemia, a hallmark of the disease, is the most common initial symptom, followed at a distance by neutropenia and thrombocytopenia. Gastrointestinal and metabolic symptoms such as failure to thrive and lactic acidosis are the most frequent non-hematological symptoms, even in the rare cases without hyporegenerative anemia. Vacuolization of BM precursors, observed in the vast majority of PS patient BMAs, is not influenced by the patient's age at sampling. Ring sideroblasts, the other feature of PS BMAs, are less frequent than progenitor vacuolization but increase significantly after 6 months of age. These abnormalities are just as common in patients with or without hematological symptoms, suggesting that BMA should be performed in all suspected PS cases, despite the absence of anemia. PS is a multisystem disorder requiring early diagnosis and a coordinate multidisciplinary management, involving clinicians and clinical biologists.
Endocrine manifestations and long-term outcomes of patients with mitochondrial diseases.
Endocrine dysfunctions are commonly associated with mitochondrial diseases. This study aimed to investigate clinical characteristics and outcomes of endocrine manifestations in patients with mitochondrial diseases. This study included 54 patients from 47 families with mitochondrial diseases who were genetically confirmed; 49 patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS), four with Pearson syndrome, and one with Kearns-Sayre syndrome (KSS). Clinical and endocrine findings were retrospectively reviewed. The median age at diagnosis was 18.5 years (range, 0.1 - 49 years). In 49 patients with MELAS, the mean height and weight standard deviation scores were - 2.0 ± 1.3 and - 2.6 ± 1.6, respectively, with 44.9% (n = 22) of the patients exhibiting short stature at diagnosis. Twenty-three (46.9%) patients with MELAS were diagnosed with diabetes mellitus (DM) at a median age of 26 years (range, 12 - 50 years). Interestingly, papillary thyroid cancer was observed in 10.2% of patients (n = 5) with MELAS at a mean age of 34.1 ± 6.9 years. One patient with MELAS and one with KSS exhibited hypoparathyroidism. Patients with Pearson syndrome and KSS exhibited more severe short stature. Adrenal insufficiency was noted in 50% of the patients with Pearson syndrome. In 20% of patients with MELAS, endocrine dysfunctions including having a short stature, DM, and hypoparathyroidism preceded the onset of neurological manifestations. Papillary thyroid cancer occurred in 10% of patients with MELAS. Patients with Pearson syndrome and KSS showed profound growth retardation and multisystem dysfunctions, such as chronic kidney disease and neurological defects, which contributed to increased mortality.
