Exemplifying a measurement validation strategy for rare- and ultra-rare diseases: measuring what matters in alpha-mannosidosis.

Orphanet journal of rare diseases2026 Feb 11

Outcomes assessment in rare and ultra-rare diseases can be hampered by the paucity of condition-specific patient-reported outcome (PRO) measures that are known to be reliable, valid, and fit for purpose. It would be helpful to develop a strategy for measuring what matters to patients/caregivers in rare and ultra-rare diseases and for validating this measurement approach even with the constraint of very small samples. The present work aims to propose a measurement strategy that builds on a conceptual measurement model of core concerns in the context of an ultra-rare lysosomal storage disorder, namely Alpha-Mannosidosis (AM). Beginning with a comprehensive literature review of what is known about AM, we identified key domains to be assessed. We drafted items for use in a video-conferenced semi-structured interview to assess symptoms in all of the relevant domains. We then identified generic, validated proxy-reported evaluative tools to assess as many of these domains as possible for use in a web-based survey. Using data collected from caregivers of individuals with AM, we then evaluated aspects of validity of the interview and survey modes of data collection. The study sample included 16 AM caregivers reporting on the disease experience of 20 individuals with AM ranging in age from 4 to 49 years old. The new assessment package’s “validation” relied on a more qualitative or visual summary of the many aspects of validity, including content validity, criterion-related validity, known-groups validity, convergent and divergent validity, and longitudinal construct validity (i.e. responsiveness). It integrated information from causal (symptom measures) and effect (evaluative PRO measures) indicators to describe what quality of life concerns are linked to the AM symptom experience. Our approach emphasized effect sizes over p-values. This study provides a roadmap for creating meaningful outcome assessment in the context of rare and ultra-rare disease. This measurement strategy yielded an empirically-based description of the multidimensional impact of AM and characterized treatment benefits more comprehensively. The new assessment package might be used in longitudinal cohort or registry studies to capture the natural history of this ultra-rare disease, could inform future clinical trials, and capture real-world efficacy outcomes of targeted treatments.

Automated bone age assessment in rare pediatric growth disorders: a comparative study using Deeplasia.

Frontiers in endocrinology2026

Bone age (BA) assessment is essential for monitoring growth and maturation and guiding therapeutic interventions. While deep learning (DL) models offer high-speed automated BA prediction, their generalizability to rare pathological and diagnostically complex populations remains a significant concern. This study aims to validate the open-source DL system Deeplasia on external data from pediatric patients with various syndromic, endocrine, and lysosomal storage disorders (LSDs) and to compare its accuracy and consistency against multiple expert human raters. We retrospectively assembled 1,138 hand radiographs from multiple centers, including patients with SHOX deficiency; Noonan syndrome; Silver-Russell syndrome; Ullrich-Turner syndrome; pseudohypoparathyroidism; congenital adrenal hyperplasia (CAH); precocious puberty and precocious pseudopuberty (cohort 1); mucopolysaccharidosis types I, II, III, IV, and VI; alpha-mannosidosis; and unclassified LSDs (cohort 2). For each radiograph, BA was evaluated using the Greulich and Pyle method by two to five human experts to obtain a mean BA reference. Model performance was assessed using the mean absolute error (MAE), root mean squared error (RMSE), and 1-year accuracy for each cohort and underlying conditions, sex, and age groups. Furthermore, Deeplasia's performance was compared with that of individual raters by testing each rater and the model against the remaining experts. Deeplasia achieved a mean MAE of 5.95 months, an RMSE of 8.01 months, and a 1-year accuracy of 89.9% for cohort 1 (endocrine and syndromic conditions). For cohort 2 (lysosomal storage disorders), Deeplasia achieved a mean MAE of 7.13 months, an RMSE of 9.56 months, and a 1-year accuracy of 81.2%. In direct comparisons between Deeplasia and individual raters tested against the remaining experts, Deeplasia outperformed all human raters. Deeplasia was validated as a highly consistent, robust, and reliable tool for BA assessment in complex cases. It demonstrated superior accuracy compared with individual human raters and may assist clinicians in BA evaluation.

Unveiling alpha-mannosidosis in Iraqi children: A series of clinically and genetically characterized cases with novel MAN2B1 variant.

Molecular genetics and metabolism reports2026 Mar

Alpha-mannosidosis is a rare lysosomal storage disorder caused by MAN2B1 mutations, leading to cognitive decline, hearing loss, infections, and skeletal abnormalities. Limited data exist from the Middle East; this study describes the clinical and genetic features of affected Iraqi children. This study was conducted at Children Welfare Teaching Hospital, and Al Emamayn Al Khadimiyan Medical City Baghdad, Iraq. We retrospectively reviewed children diagnosed with alpha-mannosidosis (2017-2025). Diagnosis was confirmed by enzyme assay and MAN2B1 testing. Clinical and imaging data were collected from medical records. A total of nine children from five unrelated families were identified. The cohort included seven males and two females. The mean age at symptoms onset was 1.1 ± 0.5 years, while the mean age at diagnosis was 10.7 ± 7.6 years, indicating a diagnostic delay of approximately 9.6 ± 7.4 years. All the patients were born to consanguineous parents. The most common clinical features included psychomotor delay, sensorineural hearing loss and coarse facial features (100 % for each). Neuroimaging of the brain revealed variable findings, and skeletal radiographs showed dysostosis multiplex in 4/9 patients. Genetic testing revealed three pathogenic/likely pathogenic MAN2B1 variants, including one novel variant [c.830C > T (p.Pro277Leu)]. Our findings represent the first clinical and molecular characterization of alpha-mannosidosis in Iraqi children and reveal previously unreported genetic features in this population. It highlights that clinical and laboratory findings in our patients were largely consistent with previously published regional and international data. It demonstrates notable diagnostic delay and identified novel variants, expanding the mutational spectrum associated with the disease.

Alpha-mannosidosis due to a novel MAN2B1 truncating mutation in a Chinese patient: a new report and long-term follow-up.

Documenta ophthalmologica. Advances in ophthalmology2026 Jan 13

To report a case of α-mannosidosis with intellectual, hearing impairment and progressive retinal degeneration, supported by ten years of ophthalmic follow-up, genetic testing, and leukocyte α-mannosidase enzymatic analysis. The patient underwent serial ophthalmic examinations over a ten-year period, including best-corrected visual acuity (BCVA) testing, fundus photography, optical coherence tomography (OCT), and fundus autofluorescence (FAF), to monitor disease progression. Trio-based whole-exome sequencing (WES) was performed on the family. Variant confirmation was conducted via Sanger sequencing. To support the genetic findings, leukocyte α-mannosidase activity was measured using fresh peripheral blood samples. At first presentation, BCVA was 20/50 OD and 20/40 OS. Over the next decade, vision progressively declined to 20/200 in both eyes. Fundus images showed granular pigment mottling in the posterior pole, and subsequent wide-angle imaging detected bone-spicule pigmentation deposits in peripheral retina. OCT demonstrated progressive retinal thinning, with loss of the ellipsoid zone. FAF revealed expanding areas of retinal atrophy. The patient has presented with bilateral sensorineural hearing loss, delayed speech development, persistent dysarthria, mild cognitive impairment, and coarse facial features since childhood. Genetic analysis identified a novel homozygous MAN2B1 mutation: c.1316_1327delinsTGATG (p.Ala439Valfs*36), inherited from consanguineous parents with the same heterozygous genotypes. The variant was classified as pathogenic based on ACMG criteria. The patient's leukocyte α-mannosidase activity was profoundly decreased, confirming the diagnosis. This case highlights the progressive nature of retinal degeneration in α-mannosidosis and underscores the diagnostic value of leukocyte enzyme testing alongside genetic and ophthalmic assessments. Early recognition of ophthalmic signs, particularly in patients with syndromic features such as hearing loss and facial dysmorphism, is essential for timely diagnosis and intervention.
