Síndrome de pterígio do pescoço-perturbação do desenvolvimento intelectual-anomalias digitais
ORPHA:2988CID-10 · Q87.0OMIM 600159DOENÇA RARA

A síndrome Pterygium colli-deficiência intelectual-anomalias digitais é caracterizada por pterígio do pescoço (uma prega de pele no pescoço), alterações nos dedos (como polegares menores que o normal, juntas dos dedos mais largas e as pontas dos dedos também mais largas) e anomalias na cabeça e no rosto. Estas anomalias incluem: cabeça com formato mais curto e largo, dobras de pele nos cantos internos dos olhos, sobrancelhas angulosas, os cantos externos dos olhos com inclinação para cima, pálpebra caída, olhos mais afastados que o normal e orelhas mais salientes, posicionadas mais abaixo e viradas para trás. Essa condição foi descrita em uma mulher e seu filho, mas os sintomas eram muito menos graves na mãe. O filho também apresentava deficiência intelectual. A transmissão da doença pode ser dominante ligada ao cromossomo X ou autossômica dominante.

Non-pterygium Escobar syndrome from compound-heterozygous CHRNG variants: genotype-phenotype insights.

Human genome variation2026 Mar 14

Escobar syndrome is a rare congenital disorder characterized by contractures, pterygia and craniofacial anomalies. Here we report a school-age girl harboring compound-heterozygous CHRNG variants, NM_005199.5:c.[2T>C];[428C>G] p.[(Met1?)];[(Pro143Arg)]. She presented with neonatal asphyxia, congenital limb contractures and low-frequency hearing loss but without pterygia, maintaining normal cognition. This case underscores the phenotypic variability of CHRNG-related disease and alerts clinicians to recognize milder presentations that lack pterygia and to consider targeted genetic testin.

Scoliosis in Escobar Syndrome: Retrospective Review of Surgical Outcomes, Risks, and Radiographic Patterns.

Journal of pediatric orthopedics2026 Mar 03

Escobar syndrome (ES) is a rare, nonlethal form of multiple pterygium syndrome, primarily characterized by joint contractures, pterygium formation, craniofacial anomalies, and scoliosis. Although scoliosis is frequently reported in ES, there is limited literature describing the broader spectrum of clinical comorbidities and intraspinal abnormalities. This study presents the largest reported cohort of ES patients to date, aiming to characterize their orthopaedic manifestations, scoliosis prevalence, and neurological anomalies. A retrospective review was conducted at a single pediatric institution from 2000 to 2024. Patients with a confirmed diagnosis of ES and scoliosis were included, with a minimum of 2 years of follow-up. Data collected included demographics, clinical comorbidities (pulmonary, cardiac, craniofacial), radiographic findings, spinal deformities, intraspinal anomalies on MRI, surgical interventions, and complications. Twenty patients met the inclusion criteria. Craniofacial anomalies were present in 100% of patients, while pulmonary disorders (43%) and cardiac anomalies (23%) were also common. Intraspinal anomalies were identified in 50% of patients, including a tethered spinal cord in 40%. Fourteen patients (70%) underwent spinal surgery at a mean age of 7 years (range, 1 to 14) with a mean follow-up of 7 years (range, 2 to 14). In all, 14 patients had spinal surgery, including 10 patients with growth-friendly procedures and 4 patients with an instrumented posterior spinal fusion (iPSF). The mean major curve improved from 77 degrees (range, 16 to 113) at initial presentation to 51 degrees (range, 18 to 110) at final follow-up. VEPTR was associated with the highest complication rate (7/3 patients, 233%), followed by MCGR (2/6 patients, 33%) and PSF (1/4 patients, 25%). Scoliosis is a common and often severe orthopaedic manifestation in patients with Escobar syndrome, frequently accompanied by a variety of comorbidities and intraspinal anomalies such as a tethered spinal cord. Surgical correction using growth-friendly techniques can be effective, but complication rates with VEPTR remain high. These findings highlight the importance of thorough preoperative imaging and thoughtful surgical planning. Level IV, therapeutic/prognostic studies.

Associations of Karyotype and Age at Diagnosis with Physical Features and Comorbidities in Turner Syndrome: A Single-Site Experience.

The application of clinical genetics2025

Turner syndrome (TS) is one of the most common genetic diseases in females, with typical physical features and comorbidities. Karyotype-phenotype associations and clinical significance of childhood versus adolescent/adulthood diagnosis are conflicting. Determining the role of certain TS karyotypes and early (<12 years of age) vs late (≥12 years) diagnosis in TS-specific phenotype and comorbidity penetrance. Retrospective analysis of baseline characteristics and 45 TS-specific features and comorbidities of 75 TS patients were diagnosed between 2009 and 2019 and followed-up until 2023 in our tertiary care center. Thirteen different karyotypes were detected: 45,X,inv(10), 45,X,inv(9)(15), 45,X, 46,X,i(Xq), 46,X,del(Xp), 46,XX,del(X)q21, 45,X/46,X,del(X), 45,X/46,X,+mar, 45,X/46,X,rX, 45,X/46,XX, 45,X/46,XY, 45,X/47,XXX, 46,X,i(Xq)/47,XX,i(Xq). The classic karyotype with 45X monosomy showed an increased risk for hypertrichosis (28.6% vs 7.5%, OR 4.93, 95% CI [1.23-19.73]), pterygium colli (34% vs 12%, OR 3.65, 95% CI [1.13-11.75]) and short stature (91% vs 75%, OR 3.56 [0.89-14.17]. Mosaic karyotypes had a smaller risk of pterygium colli (OR 0.28 [0.073-1.092]) and short stature (OR 0.29 [0.086-1.026]. 45X/46XX mosaicism was associated with an increased risk of hypertension (33% vs 6%, OR 7.75 [1.39-43.08]), and the presence of the iso (Xq) chromosome increased the risk of celiac disease (28% vs 3%, OR 13.2 [1.52-114.52]). 44/75 (58.6%) of the cohort were diagnosed at <12 years of age. In the <12-year-old diagnosis group, facial dysmorphism and low hairline, (OR 3.30, [1.26-8.65]), low-set ears (OR 2.51 [0.98-6.46]), and breasts abnormalities (OR 4.71 [1.72-12.83]), short stature (OR 4.09 [1.13-14.82]) and GH therapy (OR 4.93 [1.31-16.01]) occurred more frequently. If diagnosed <12 years, patients had a decreased risk of hepatosplenomegaly (OR 0.10 [0.02-0.50]) and hypertension (OR 0.097 [0.01-0.85]). TS patients should be handled as a heterogenous group, as they seem to differ in the penetrance of phenotypical features of the disease and the risk of comorbidities depending on karyotype and age at diagnosis.

Distinct IRF6 dysfunction mechanisms in syndromic orofacial clefts: Computational evidence for allosteric versus direct disruption.

Computational and structural biotechnology journal2025

Orofacial clefts (OC) are a congenital anomaly typically classified as syndromic or non-syndromic. Among the syndromic cases, Van der Woude syndrome (VWS) and popliteal pterygium syndrome (PPS) are primarily caused by pathogenic variants in IRF6, which encodes a transcriptional factor essential for orofacial development. Our aim is to identify and characterize IRF6 variants in two syndromic OC cases and assess their structural and functional consequences through computational modeling. Sequencing of IRF6 exons 3, 4, 7, and 9 was conducted in one proband with VWS and one proband with PPS, as well as their parents. Structural impacts were measured through comparative modeling based on the IRF4-DNA complex, followed by molecular dynamics simulations. Binding free energies and protein-DNA interactions were assessed using MM/GBSA calculations and hydrogen bond occupancy analysis. We identified two pathogenic variants: NP_006138.1:p.(Ala16Val) in a VWS proband and NP_006138.1:p.(Arg84Cys) in a PPS proband, both confirmed as de novo. Variants were classified as pathogenic by the American College of Medical Genetics and Genomics criteria, and by most pathogenicity predictors. Molecular dynamics simulations showed that NP_006138.1:p.(Ala16Val) induces long-range allosteric effects with increased structural fluctuations, while NP_006138.1:p.(Arg84Cys) directly disrupts critical DNA-binding interactions. MM/GBSA analysis demonstrated reduced DNA-binding affinity for both variants, with NP_006138.1:p.(Arg84Cys) showing the most severe electrostatic disruption. Our computational analyses suggest that pathogenic IRF6 variants may impact DNA binding through distinct molecular mechanisms: NP_006138.1:p.(Ala16Val) potentially through allosteric conformational changes and NP_006138.1:p.(Arg84Cys) likely through direct disruption of the protein-DNA interface.

Novel heterozygous mutation in MYH3 causes contractures, pterygia, and spondylocarpostarsal fusion syndrome 1: A case report.

Medicine2025 Aug 08

Contractures, pterygia, and spondylocarpotarsal fusion syndrome (CPSFS) comprises a group of extremely rare genetic disorders characterized by congenital craniofacial and musculoskeletal abnormalities. With fewer than 500 cases reported globally, this scarcity contributes to limited clinical recognition, frequent diagnostic delays or errors, and missed opportunities for timely intervention. We present this case to enhance awareness of CPSFS and report a novel pathogenic variant in MYH3 (previously undocumented in the literature) that broadens the known mutational spectrum of MYH3 and enriches the phenotypic profile of CPSFS. A female neonate was born at 29 weeks, prenatal ultrasound and magnetic resonance imaging revealed scoliosis and vertebral fusion. The postnatal examination showed microstomia, low-set ears, a short neck with webbing, and flexion contractures at shoulders, elbows, knees, and hands. The whole genome sequencing found novel variants, namely NM_002470.4: c.1914del C; p. Lys639Argfs*18 and NM_002470.4: c.-68 + 4A > T, in the MYH3. CPSFS 1. Immediately after birth, noninvasive ventilatory support was initiated. The surgical team conducted comprehensive evaluations, while concurrent genetic testing was performed. Given the infant's multiple systemic skeletal malformations and inability to sustain spontaneous respiration, surgical intervention was deemed nonviable. Due to severe thoracic deformity and bronchopulmonary dysplasia, the infant required continuous noninvasive ventilation from birth and remained ventilator-dependent. At a corrected gestational age of 36 weeks and 4 days, life-sustaining therapy was withdrawn following thorough counseling and parental deliberation. The infant died shortly thereafter. Prenatal ultrasound and fetal magnetic resonance imaging can reliably detect characteristic manifestations including scoliosis, joint developmental abnormalities, and clubfoot. Thus, regular prenatal surveillance plays a critical role in early disease identification. For suspected cases, genetic counseling and diagnostic testing enable informed parental decision-making regarding management of affected offspring and future reproductive planning.
