Introdução
O que você precisa saber de cara
Síndrome de Noonan com múltiplas lentiginas (anteriormente chamada síndrome LEOPARD) é uma condição que afeta muitas áreas do corpo. Como o nome da condição sugere, a síndrome de Noonan com múltiplas lentiginas é muito semelhante a uma condição chamada síndrome de Noonan, e pode ser difícil distinguir os dois distúrbios na primeira infância. No entanto, as características desses dois quadros diferem mais tarde na vida. As características típicas da síndrome de Noonan com múltiplas lentiginas incluem manchas marrons na pele chamadas lentiginas, que são semelhantes a sardas, defeitos cardíacos, olhos amplamente espaçados (hipertelorismo ocular), peito afundado (pectus excavatum) ou peito protuberante (pectus carinatum) e baixa estatura. Essas características variam, porém, mesmo entre indivíduos afetados na mesma família. Nem todas as pessoas com síndrome de Noonan com múltiplas lentiginas apresentam todas as características típicas desta condição.
As lentiginas observadas na síndrome de Noonan com múltiplas lentiginas geralmente aparecem pela primeira vez na infância média, principalmente no rosto, pescoço e parte superior do corpo. As pessoas afetadas podem ter milhares de pequenas manchas marrons escuras na pele ao atingirem a puberdade. Ao contrário das sardas, o surgimento das lentiginas não tem relação com a exposição ao sol. Além das lentiginas, pessoas com esta condição podem ter manchas marrons mais claras chamadas manchas café-au-lait. As manchas café-au-lait tendem a se desenvolver antes das lentiginas, aparecendo dentro do primeiro ano de vida na maioria das pessoas afetadas.
Das pessoas com síndrome de Noonan com múltiplas lentiginas que apresentam defeitos cardíacos, cerca de 80 % têm cardiomiopatia hipertrófica, que é um espessamento do músculo cardíaco que obriga o coração a trabalhar mais para bombear sangue. A cardiomiopatia hipertrófica costuma afetar mais frequentemente o compartimento inferior esquerdo do coração (o ventrículo esquerdo). Até 20 % das pessoas com síndrome de Noonan com múltiplas lentiginas que têm problemas cardíacos apresentam um estreitamento da artéria que vai do coração para os pulmões (estenose pulmonar).
Pessoas com síndrome de Noonan com múltiplas lentiginas podem ter uma aparência facial distintiva. Além do hipertelorismo ocular, os indivíduos afetados podem apresentar pálpebras caídas (ptose), lábios grossos e orelhas baixas. Os indivíduos afetados também costumam ter uma aparência anormal do peito; eles têm pectus excavatum ou pectus carinatum.
Ao nascer, pessoas com síndrome de Noonan com múltiplas lentiginas geralmente têm peso e altura normais, mas em alguns casos o crescimento diminui ao longo do tempo. Esse crescimento lento resulta em indivíduos afetados sendo mais baixos que a média, embora menos da metade das pessoas com síndrome de Noonan com múltiplas lentiginas tenham estatura significativamente baixa.
Outros sinais e sintomas da síndrome de Noonan com múltiplas lentiginas incluem perda auditiva causada por anomalias no ouvido interno (surdez sensorioneural), deficiência intelectual leve e dobras extras de pele na parte posterior do pescoço. Homens afetados frequentemente apresentam anomalias genitais, que podem incluir testículos não descendidos (criptorquidia) e uma uretra que se abre na parte inferior do pênis (hipospadia). Essas anomalias podem reduzir a capacidade de ter filhos biológicos (fertilidade diminuída). Mulheres com síndrome de Noonan com múltiplas lentiginas podem ter ovários pouco desenvolvidos e puberdade tardia.
A síndrome de Noonan com múltiplas lentiginas é uma de um grupo de condições relacionadas coletivamente conhecidas como RASopatias. Essas condições têm sinais e sintomas semelhantes e são causadas por alterações na mesma via de sinalização celular. Além da síndrome de Noonan com múltiplas lentiginas, as RASopatias incluem síndrome de Noonan, síndrome cardiofaciocutânea, síndrome de Costello, neurofibromatose tipo 1 e síndrome de Legius.

Clinical phenotypes and cochlear implant outcomes in patients with PTPN11-associated noonan spectrum disorders: Insights from a genetically screened cohort.
We characterized the clinical features of PTPN11-related deafness and evaluated the outcomes of cochlear implantation in affected patients. Whole-exome sequencing and bioinformatic analyses were performed in a cohort of 467 individuals with congenital sensorineural hearing loss to identify potential genetic etiologies. Four patients harboring PTPN11 variants were reviewed for their clinical characteristics and post-implantation auditory rehabilitation outcomes. PTPN11 variants were identified in four patients (Cases 1-4). A missense variant c.1391G > C (p.Gly464Ala) in exon 12 was detected in Case 1 and the recurrent variant c.836A > G (p.Tyr279Cys) in exon 7 was identified in Case 2. Both patients were diagnosed with Noonan syndrome with multiple lentigines. Missense variants c.1510A > G (p.Met504Val) in exon 13 and c.923A > G (p.Asn308Ser) in exon 8 were found in Cases 3 and 4, respectively; both were diagnosed with Noonan syndrome. Cases 1, 2, and 4 underwent cochlear implantation and demonstrated favorable postoperative auditory and speech outcomes. Our study provides a comprehensive characterization of auditory, speech and systemic phenotypes in PTPN11-related Noonan spectrum disorders and demonstrates that cochlear implantation is highly effective for severe-to-profound hearing loss. These findings emphasize the value of early genetic diagnosis and emphasize the importance of coordinated, interdisciplinary management.
Noonan Syndrome With Multiple Lentigines Mimicking Obstructive Hypertrophic Cardiomyopathy Treated by Septal Myectomy.
Noonan syndrome with multiple lentigines (NSML) is a rare RASopathy characterized by lentigines, craniofacial anomalies, and cardiac involvement. Hypertrophic cardiomyopathy (HCM) with left ventricular outflow tract obstruction is a frequent phenotype and may require interventional therapy. We present a 43-year-old woman with NSML and obstructive HCM. Despite optimized pharmacologic therapy and implantable cardioverter-defibrillator implantation, she developed progressive dyspnea and palpitations. Multidisciplinary heart team evaluation favored surgical septal myectomy with papillary muscle plasty, given unfavorable anatomy for alcohol septal ablation. Postoperative echocardiography showed marked gradient reduction and symptom relief. Approximately 5% to 10% of patients with HCM remain refractory to medical therapy. In phenocopies such as NSML, therapeutic decisions should be individualized. Surgical myectomy is a safe alternative when septal anatomy precludes alcohol septal ablation. Septal reduction therapies may be considered in NSML with left ventricular outflow tract obstruction. Heart team discussion is essential. Surgical myectomy can provide sustained functional improvement.
Development and Treatment of Severe Lordoscoliosis in a Patient With Noonan Syndrome With Multiple Lentigines (NSML): A Case Report.
Noonan syndrome with multiple lentigines (NSML) is an allelic variant of Noonan syndrome (NS), which can exhibit multisystemic features, including sensorineural hearing loss (SNHL) and skeletal anomalies. We report on a patient with this rare condition who developed an uncommon syndromic feature of severe lordoscoliosis requiring surgical intervention, whose comorbidities complicated the perioperative course, including the preclusion of magnetic resonance imaging (MRI) and relative contraindication to transcranial motor evoked potentials (TcMEPs). We discuss the use of preoperative computed tomography (CT) and somatosensory evoked potentials (SSEPs) in facilitating the consent process for surgery where MRI and TcMEPs are impracticable, as well as the intraoperative measures taken to minimise complications in this case. We also highlight the importance of multispecialty, multidisciplinary involvement in the management of such patients. In this patient whose severe lordoscoliosis led to persistent back pain and airway compression, posterior spinal fusion achieved satisfactory deformity correction and excellent clinical outcome, which was maintained at follow-up.
Genotype-Phenotype Analysis and New Clinical Findings in a Series of 24 Patients Presenting with Noonan Syndrome and Related Disorders.
RASopathies are a heterogeneous group of conditions of the RAS/mitogen-activated protein kinase pathway presenting with overlapping features such as growth deficiency, neurodevelopmental disorders, cardiac defects, craniofacial dysmorphisms, cutaneous and ocular abnormalities, and increased cancer risk. This retrospective study analyzed the medical records regarding clinical and molecular data from 2018 to 2024 in a single center for rare diseases of individuals diagnosed with Noonan syndrome and related disorders previously submitted to diagnostic molecular analysis through next-generation sequencing techniques. Twenty-four patients were enrolled with an even sex ratio distribution and ages ranging from 1 month to 16 years at first evaluation. The main reason for referral was diagnostic assessment due to a combination of dysmorphic features (24/24; 100%), growth deficiency (18/24; 75%), neurodevelopmental disorders (15/24; 62.5%), and/or heart disease (13/24; 54.1%). Final diagnoses included 15 individuals with Noonan syndrome (nine with variants in PTPN11, two in SOS1, and one each in LZTR1, A2ML1, and MRAS, besides one with variants in both LZTR1 and SOS1), two with Noonan syndrome with multiple lentigines (both with variants in PTPN11), two with Neurofibromatosis-Noonan (NF1), two with cardiofaciocutaneous syndrome (BRAF), and one each with Noonan syndrome-like with loose anagen hair (PPP1CB), Noonan syndrome-like (CBL), and Costello syndrome (HRAS); one individual presented with a double diagnosis of Noonan and Klinefelter syndromes. Three pairs of unrelated patients presented recurrent variants in the PTPN11 gene, partially concordant in phenotypic correlation among the pairs but not fully concordant compared to previously described cases in the literature. Undescribed features in this group included myopathy and megacolon in a patient with Noonan syndrome-like, hypogonadotropic hypogonadism, and azoospermia in a patient with Noonan syndrome-like with loose anagen hair, and schizophrenia in a patient with Costello syndrome. One patient with Noonan syndrome had a novel variant of the A2ML1 gene (c.1829G>A), but the variant was strictly of uncertain significance, while c.2033G>A in the LZTR1 gene and c.1A>G in the NF1 gene are variants for the first time associated with features of Noonan syndrome.
Dysregulated TGFβ-ERK Signaling Drives Aberrant Extracellular Matrix Production in Noonan Syndrome-Associated Pulmonary Valve Stenosis.
Pulmonary valve stenosis (PVS) is the most common congenital heart defect in Noonan syndrome (NS) and related RASopathies, yet the molecular mechanisms linking pathogenic variants to the valve pathology remain poorly defined. Here, we utilized a human iPSC-based valve differentiation platform to generate the cardiac valve cell lineages-including fibrosa and spongiosa valve interstitial cell (VIC) subtypes. CRISPR-edited iPSCs harboring NS gain-of-function RAS/MAPK and Noonan syndrome with multiple lentigines (NSML) dominant-negative RAS/MAPK variants exhibited early defects in mesodermal and endocardial specification in all genotypes. Additionally, NS-iPSC endocardial cells exhibited defects in endothelial-to-mesenchymal transition (EndMT) specifically towards fibrosa VICs, which was most pronounced in PTPN11 N308D (N308D) cells. Single-cell transcriptomics revealed widespread dysregulation of extracellular matrix (ECM) programs in N308D fibrosa VICs, including increased expression of collagens and proteoglycans, as well as dysregulation of multiple genes involved in ECM remodeling. We also detected activation of RAS-MAPK, TGFβ, and fibrosis-associated pathways in our transcriptional dataset. Mass spectrometry-based phosphoproteomics confirmed coordinated increases in ERK, PKC, and stress-related kinases, as well as enhanced activity of the TGFβ receptor. Functionally, N308D fibrosa VICs exhibited exaggerated upregulation of ECM genes in the presence of TGFβ2 ligand, suggesting that these cells are hypersensitive to TGFβ stimulation. Furthermore, we demonstrated that this pathological ECM-program occurs independently of BAMBI, a negative regulator of TGFβ signaling that was found to be decreased in N308D fibrosa VICs. Lastly, we performed histopathological analyses of stenotic pulmonary valves from two NS infants, which demonstrated marked overproduction and disorganization of ECM, mirroring the findings from our iPSC-based disease model. Together, our data reveal a central mechanism where NS-associated alleles sensitize fibrosa VICs to TGFβ, which leads to aberrant downstream signaling and drives the pathological ECM program in NS-associated PVS.
