A Amaurose Congênita de Leber (ACL) é uma doença da retina (a parte do olho que capta a luz) que causa cegueira. Ela é diagnosticada quando as respostas a exames que medem a atividade elétrica da retina (como o eletroretinograma de Ganzfeld, ou ERG) estão muito abaixo do normal ou são praticamente inexistentes. A condição está associada a uma perda visual grave que surge já no primeiro ano de vida da criança.

Introdução

O que você precisa saber de cara

💬
EM LINGUAGEM SIMPLES

Leber congenital amaurosis, também conhecida como LCA, é um distúrbio ocular que está presente desde o nascimento (congênito). Esta condição afeta principalmente a retina, que é o tecido especializado na parte posterior do olho que detecta luz e cor. Pessoas com a condição geralmente apresentam comprometimento visual grave que começa ao nascer ou logo depois. O comprometimento visual tende a ser severo e pode piorar ao longo do tempo.

Leber congenital amaurosis também está associada a outros problemas de visão, incluindo sensibilidade aumentada à luz (fotofobia), movimentos involuntários dos olhos (nistagmo) e hipermetropia extrema (hipermetropia). As pupilas, que normalmente se dilatam e contraem em resposta à quantidade de luz que entra no olho, não reagem normalmente à luz. Em vez disso, elas se dilatam e contraem mais lentamente que o normal, ou podem não responder à luz de forma alguma.

Um comportamento específico chamado sinal oculo-digital de Franceschetti é característico da Leber congenital amaurosis. Esse sinal consiste em indivíduos afetados cutucando, pressionando e esfregando os olhos com um nódoa ou dedo. Cutucar os olhos frequentemente resulta na sensação de flashes de luz chamados fosfenos. Pesquisadores suspeitam que esse comportamento pode contribuir para olhos mais fundos em crianças afetadas.

Em casos muito raros, atraso no desenvolvimento e deficiência intelectual foram relatados em pessoas com as características da Leber congenital amaurosis. Por causa da perda visual, crianças afetadas podem tornar‑se isoladas. Oferecer às crianças oportunidades de brincar, ouvir, tocar, compreender e outras intervenções educacionais precoces pode prevenir atrasos no desenvolvimento em crianças com Leber congenital amaurosis.

Pelo menos 20 tipos genéticos de Leber congenital amaurosis foram descritos. Os tipos são diferenciados pela causa genética, pelos padrões de perda visual e pelas anomalias oculares relacionadas.

Short-rib thoracic dysplasia 9 with or without polydactyly

A form of short-rib thoracic dysplasia, a group of autosomal recessive ciliopathies that are characterized by a constricted thoracic cage, short ribs, shortened tubular bones, and a 'trident' appearance of the acetabular roof. Polydactyly is variably present. Non-skeletal involvement can include cleft lip/palate as well as anomalies of major organs such as the brain, eye, heart, kidneys, liver, pancreas, intestines, and genitalia. Some forms of the disease are lethal in the neonatal period due to respiratory insufficiency secondary to a severely restricted thoracic cage, whereas others are compatible with life. Disease spectrum encompasses Ellis-van Creveld syndrome, asphyxiating thoracic dystrophy (Jeune syndrome), Mainzer-Saldino syndrome, and short rib-polydactyly syndrome. SRTD9 is characterized by phalangeal cone-shaped epiphyses, chronic renal disease, nearly constant retinal dystrophy, and mild radiographic abnormality of the proximal femur. Occasional features include short stature, cerebellar ataxia, and hepatic fibrosis.

Establishment of an induced pluripotent stem cell line from a patient with Leber Congenital Amaurosis.

Stem cell research2026 Apr

A human induced pluripotent stem cell (hiPSC) line BTHBIOi006-A was generated from peripheral blood mononuclear cells of a patient carrying RDH12 biallelic mutations via episomal reprogramming. The line exhibits a normal karyotype, expresses pluripotent markers, differentiates into three germ layers, and is mycoplasma-free, serving as a tool for retinal disease research.

Functional In Vitro Assessment of rAAV-Delivered Retinol Dehydrogenase 12 (RDH12) Activity.

International journal of molecular sciences2026 Jan 29

Gene replacement therapy can be used for the treatment of hereditary retinopathies, such as retinol dehydrogenase 12 (RDH12)-associated Leber congenital amaurosis 13 (LCA13); however, the lack of animal models accurately mimicking the human disease phenotype requires the initial in vitro confirmation of therapy efficacy. Two synthetic serotypes (2.7m8 and PHP.S) of adeno-associated virus (AAV) were tested against the natural serotypes (5 and 9) with the aim of increasing the transduction efficiency and delivery of the green fluorescent protein (GFP) in HEK293 and ARPE-19 cells. The three most efficient serotypes were then used for the delivery of RDH12, followed by the assessment of its functional activity in the transduced cells. In the in vitro test system, a cassette encoding GFP and the wild-type (wt) RDH12 was delivered into ARPE-19 and HEK293 cells by rAAV 5, PHP.S, and 7m8 at 30K and 60K VG/cell. RDH12 mutants pThr155Ile (RDH12mut) and Met1* (RDH12sc) were used to mimic the RDH12-associated pathology. Transduction efficiency and protein expression were assessed by flow cytometry, fluorescence microscopy, and Western blotting. Percentages of AAV7m8-transduced GFP+ cells 1.5- and 6.4-times higher were observed as compared to AAV5 and AAV.PHP.S, respectively. 4-hydroxynonenal (4-HNE), more toxic to the cells with dysfunctional RDH12, was used on cells expressing the three RDH12wt versions. Following treatment with 100 μM 4-HNE, 2.6 (AAV5) and 8.8 (AAV7m8) times more cells co-expressing RDH12wt and GFP were alive as compared to the cells expressing only GFP. The number of live RDH12wt-expressing cells was also 32 and 9.6 times higher than that of RDH12sc-expressing cells and the negative control (NC), respectively. The developed approach enables the functional assessment of RDH12 replacement therapy only in rAAV-transduced cells and demonstrates that rAAV7m8 is the most efficient serotype for this purpose.

Biallelic germline variants in the hematologic malignancy predisposition gene DDX41 cause retinal dystrophy through dysregulation of retinal homeostasis.

medRxiv : the preprint server for health sciences2026 Jan 30

Leber congenital amaurosis (LCA) and Early-onset severe retinal dystrophy (EOSRD) manifest within the first months and the first years of life, respectively. They are the leading cause of severe vision impairment in childhood. Using next generation sequencing, we identified eight families of patients with LCA/EOSRD carrying biallelic combination of six germline variants in DDX41 , encoding a DEAD-box ATPase RNA helicase involved in RNA splicing, innate immunity and hematopoiesis. In fibroblasts from a patient carrying the homozygous missense variant c.1187T>C (p. Ile396Thr) and in the retina of Ddx41 I396T/I396T mice, DDX41 protein expression was decreased. Electroretinogram recordings in these animals also revealed significant visual dysfunction since the first month of age, supporting a pathogenic role of DDX41 in retinal physiology. Immunohistochemical staining showed that the protein localized to nuclei in all major retinal cell types and to photoreceptor synapses, while biochemical assays showed that LCA/EOSRD variants disrupt DDX41 interactions with RNA through misfolding or the formation of non-productive aggregates, resulting in loss-of-function. Transcriptomic profiling of mutant mouse retinas revealed dysregulation of gene networks associated with Müller cells (MCs), glial cells essential for maintaining retinal structure, metabolic balance, and immune surveillance. The dysregulated pathways chiefly involved cell morphogenesis and junction formation, consistent with immunohistological analyses of widespread architectural disruption and nuclear disorganization, identifying MCs as a site of dysfunction. Together, these findings establish for the first time the involvement of DDX41 in LCA/EOSRD and provide new insights into the role of helicases in retinal homeostasis.

Combination gene therapy with AAV based RPE65 and survivin vectors sustains phenotypic rescue in neural retina of LCA2 mice.

Molecular and cellular biochemistry2026 Feb 03

Leber congenital amaurosis type 2 (LCA2) is an inherited retinal disorder, with severe vision impairment in children, progressing to complete blindness in the later stages of life. The current approved treatment involves Adeno-associated virus (AAV) vector serotype 2-based subretinal delivery of human RPE65 gene. However, long-term follow-up have reported gradual loss of phenotypic response. To overcome this, we have pursued strategies aimed at improving the transduction efficacy of the vector, optimizing the transgene for enhanced protein expression and co-delivering the therapeutic vector along with the anti-apoptotic factor, Survivin /baculoviral IAP repeat containing 5 (BIRC5) gene in the neural retina. We tested the efficacy of modified RPE65 transgene (Kozak/ codon optimized [CodOpt]) carried by an improved AAV2 vector (AAV2K665Q) against RPE65 wild type (WT) and observed that vector carrying CodOptRPE65 performed 1.8-fold better in vitro. Subsequently, the codon optimized RPE65 transgene containing vector was evaluated in a pre-clinical mouse model of LCA2 (rd12) with co-delivery of Survivin in an AAV5 vector. Animals were monitored for up to 6 months, and electroretinography revealed improved A- and B-wave response of 2.57- fold and 1.76-fold, respectively in combination treated eyes (CodOptRPE65 + Survivin) as compared to mock group. Co-delivery of CodOptRPE65 + Survivin did not significantly enhance retinal function by ERG when compared to AAV2K665Q-CMV-codon-optimized RPE65 alone. However, immunohistochemistry revealed that expression of apoptotic marker Bax is significantly reduced and anti-apoptotic marker Bcl2 significantly increased in animals receiving the combination therapy. A TUNEL assay further confirmed the decrease in apoptosis in the combination treatment group. These findings suggest that incorporating anti-apoptotic factors may strengthen the phenotypic rescue and control degeneration of the neural retina in LCA2 patients, offering a promising avenue for future clinical implementation.

Novel Genotype-Phenotype Correlations in CRB1-Retinopathies: Insights from Isoforms and Protein Domains Linked to Disease Severity.

Ophthalmology science2026 Feb

This study evaluates genotype-phenotype correlations in CRB1-retinopathies using standardized phenotypic classification and comprehensive analysis of Crumbs homolog 1 (CRB1)-A and CRB1-B involvement alongside in silico protein modeling analysis. Retrospective multicenter cohort study. A total of 389 patients with biallelic disease-causing CRB1 variants from 50 international cohorts, including 73 patients from Moorfields Eye Hospital. Phenotypes were reclassified using standardized diagnostic criteria. Genotype-phenotype correlations were assessed based on CRB1 isoform involvement and protein domain localization of variants, supported by in silico structural modeling. Associations between CRB1 variant location, isoform involvement, and clinical phenotypes including Leber congenital amaurosis/early onset severe retinal dystrophy (LCA/EOSRD), retinitis pigmentosa (RP), cone-rod dystrophy, and macular dystrophy (MD). All patients had variants affecting CRB1-A, with none exclusively affecting CRB1-B. Mutations specific to CRB1-A, sparing CRB1-B were associated with MD. Mutations in exons 6, 7, and 9 were associated to LCA/EOSRD and RP phenotypes, whereas exon 2 variants were linked to MD. Genotype-phenotype correlations included c.1841G>T p.(Gly614Val) linked to LCA/EOSRD and variants exclusively involving exon 11 and 12. Similarly, the variants c.2506C>A p.(Pro836Thr) and c.498_506del p.(Ile167_Gly169del) were linked to MD. Crumbs homolog 1-A must be affected for disease manifestation, while sparing of CRB1-B leads to milder phenotypes. Novel genotype-phenotype correlations were found using standardized phenotypic classification. Understanding protein structure and isoform involvement is crucial for accurate diagnosis, prognosis, and the development of targeted therapies.
