Experience with patients presenting with the clinical features of Holt-Oram syndrome: a single center retrospective study.
Holt-Oram syndrome, also known as atrio-digital syndrome, is a rare autosomal dominant genetic disorder primarily characterized by upper limb malformations and congenital heart defects, associated with mutations in the TBX5 gene. Diagnosis is typically based on clinical presentation, and the prognosis for affected individuals is closely related to the severity of cardiac involvement. Our study aims to highlight some key features of Holt-Oram syndrome to improve the level of clinical diagnosis. We collected 11 patients with clinical features strongly suggestive of Holt-Oram Syndrome at the First Affiliated Hospital of Tsinghua University from January 2010 to January 2025. These patients exhibited both limb malformations and cardiac abnormalities. We then analyzed the characteristics of their diseases. The skeletal abnormalities and cardiac defects presented in diverse forms among the 11 patients. Among the congenital heart diseases, atrial septal defect (ASD) was the most common, accounting for 80% of cases. However, some patients presented with severe conditions such as tetralogy of Fallot or Ebstein's anomaly. Regarding upper limb malformations, the most frequent finding was triphalangeal thumb (8/10 patients), but thumb hypoplasia or aplasia and radial bone abnormalities were also observed. The predominant cardiac structural abnormality in this group of patients was atrial septal defect. Upper limb malformations were predominantly characterized by polydactyly or syndactyly. However, arrhythmias appeared to be mainly supraventricular tachycardia, and upper limb involvement did not seem to show a clear left-sided predominance. The prognosis following cardiac corrective surgery was favorable. Nevertheless, for this condition, emphasis should be placed on prevention. Holt-Oram syndrome (HOS) is characterized by the association of upper-limb defects, congenital heart malformations, and cardiac conduction disease. Upper-limb malformations are usually bilateral/asymmetric, rarely unilateral or bilateral/symmetric, and affect the radial ray. They can range from thenar hypoplasia, triphalangeal thumb(s), or absent thumb(s) to radial agenesis/hypoplasia to phocomelia. Deformities of the carpal and thenar bones, abnormalities of the shoulders and/or elbows, and vertebral defects can occur. A congenital heart malformation is present in 90% of individuals with HOS and most commonly involves the septum. Atrial septal defect and ventricular septal defect can vary in number, size, and location. Complex congenital heart malformations can also occur in individuals with HOS. Individuals with HOS with or without a congenital heart malformation are at risk for cardiac conduction disease (30%). While individuals may present at birth with sinus bradycardia and first-degree atrioventricular (AV) block, AV block can progress unpredictably to a higher grade including complete heart block with and without atrial fibrillation. The clinical diagnosis of HOS is established by the presence in a proband of a preaxial radial ray anomaly and a personal or family history of cardiac septation and/or conduction defects. More than 70% of individuals who meet strict clinical diagnostic criteria have an identifiable heterozygous pathogenic variant in TBX5. Treatment of manifestations: Management involves a multidisciplinary team of specialists in medical genetics, cardiology, orthopedics, and hand surgery. Treatment of upper-limb malformations per orthopedist can include surgery, physical therapy, occupational therapy, and/or prostheses in those with severe limb shortening. Social and psychological support for affected individuals and families; standard treatment for congenital heart malformation per cardiologist and cardiac surgeon; anticoagulants and antibiotic prophylaxis for bacterial endocarditis if recommended by cardiologist; treatment for arrhythmias may require medication, surgery, and/or pacemaker implantation; pharmacologic treatment for individuals with pulmonary hypertension per cardiologist and/or intensivist. Surveillance: Assess limb function and activities of daily living per orthopedist, physical therapist, and/or occupational therapist; annual EKG in those at risk of developing a conduction defect; annual EKG combined with Holter monitor for individuals with known conduction disease; echocardiogram according to the absence/presence of congenital heart defect and history of heart surgery, every five years in the absence of congenital heart defects to assess for rare cardiomyopathy; surveillance in those with pulmonary hypertension per cardiologist and/or intensivist. Agents/circumstances to avoid: Certain medications may be contraindicated in individuals with arrhythmias, cardiomyopathy, and/or pulmonary hypertension. Evaluation of relatives at risk: Presymptomatic diagnosis and treatment is warranted in relatives at risk to identify those who would benefit from appropriate cardiac management. Pregnancy management: Affected women who have not undergone cardiac evaluation should do so prior to pregnancy or as soon as the pregnancy is recognized; those with a known history of a structural cardiac defect or cardiac conduction abnormality should be followed by a cardiologist during pregnancy. HOS is inherited in an autosomal dominant manner. Some individuals diagnosed with HOS have an affected parent; up to 60% of affected individuals represent simplex cases. Significant intrafamilial variability in limb and heart defect severity is observed among affected family members. Offspring of an individual with HOS have a 50% risk for HOS. If the TBX5 pathogenic variant has been identified in an affected family member, prenatal and preimplantation genetic testing are possible. If the pathogenic variant in the family is not known, prenatal ultrasound (US) examination evaluating for characteristic limb and cardiac manifestations is recommended (a normal US examination does not eliminate the possibility of HOS in the fetus).
Atypical Holt-Oram syndrome: Early-onset sick sinus syndrome in a Japanese family with a novel TBX5 mutation, Q469.
Holt-Oram syndrome (HOS; OMIM 142900) is a rare autosomal dominant disorder, typically involving upper limb anomalies and cardiac septal defects. HOS is caused by mutations in the TBX5 gene, which encodes a T-box transcription factor. We report a Japanese family with a novel TBX5-Q469* nonsense variant that exhibited atypical HOS characteristics, including early-onset sick sinus syndrome (SSS), but no apparent upper limb abnormalities. The proband required a pacemaker implantation at age 44 for SSS and repeated catheter ablation procedures for atrial fibrillation (AF). His daughter experienced AF with pauses, requiring catheter ablation and a pacemaker. Neither exhibited upper limb abnormalities or cardiac structural defects. However, the 28-year-old granddaughter of the proband, who did not undergo genetic testing, had a surgically corrected atrial septal defect at the age of 5. She also exhibits mild shortening of the fifth finger and sinus bradycardia. This study expanded the phenotypic spectrum of HOS, emphasizing the potential for a TBX5 variant to present as familial early-onset SSS without overt skeletal anomalies. These findings highlighted the need for genetic screening for TBX5 variants in cases of early-onset familial SSS and congenital heart defects. Genetic screening may enhance early diagnosis and guide individualized management strategies. Genetic testing for the TBX5 gene, the causal gene for Holt-Oram syndrome, should be considered in patients with a high prevalence of early-onset familial sick sinus syndrome and history of congenital heart disease. Even in atypical cases without obvious abnormalities of the upper extremities, this could enhance the diagnosis of Holt-Oram syndrome and guide individualized management strategies.
Rare T-box variants in adult pulmonary arterial hypertension with congenital heart disease.
We report the clinical and genetic features of three adult patients with congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH) carrying rare T-box variants. All three patients had weakness and cyanosis. Two patients had chest tightness, dry cough, and hemoptysis, and one patient had lower limb edema. Besides meeting the diagnostic criteria of CHD-PAH, three patients respectively presented the clinical features of specific syndromes. Specifically, patient 1 presented with clinical features consistent with tetralogy of Fallot, patient 2 presented with characteristics associated with small patella syndrome, and the patient 3 exhibited features consistent with Holt-Oram syndrome. Exome sequencing revealed that the TBX1 (c.820 T > C) variant was identified in patient 1, the TBX4 (c.251del) variant was detected in patient 2 and the TBX5 (c.486del) variant was found in patient 3. Our study for the first time found that CHD-PAH patients carry T-box gene variants, which has added new clues to understanding the pathogenesis of CHD-PAH and is expected to provide new targets and ideas for the diagnosis and treatment of CHD-PAH.
Polydactyly and syndactyly linked to GLI3 and TBX5 mutations: A pediatric case report.
Polydactyly and syndactyly, which are commonly encountered congenital limb deformities, rarely occur together and are linked with significant genetic mutations. This report sheds light on a unique co-presentation involving mutations in both the GLI3 and TBX5 genes, offering a deeper understanding of the genetic interactions that may influence limb development. This case report is important to increase our knowledge on genetic bases of limb malformations. We report the case of an 8-month-old boy, born to non-consanguineous parents, presenting with both polydactyly and syndactyly in his limbs, in particular, complete syndactyly between the third to fifth fingers and post-axial polydactyly of the feet. His father showed a similar phenotype. Genetic testing identified a pathogenic heterozygous variant in the GLI3 gene (c .3762 T > A, p.(Tyr1254 *)) and a variant of uncertain significance in the TBX5 gene (c .1063 C>T, p.(Arg355Cys)). This case highlights the complex nature of diagnosing and managing congenital limb deformities driven by genetic factors. It underscores the critical importance of comprehensive genetic testing in determining the etiology of limb malformations. The GLI3 variant, classified according to ACMG guidelines as a class IV mutation, likely results in a truncated protein due to a premature stop codon, confirmed by family segregation analysis indicating its paternal origin, suggesting autosomal dominant inheritance. Notably, the TBX5 gene variant, often associated with Holt-Oram syndrome-which is characterized by only hand skeletal anomalies and early-onset atrial fibrillation-suggests a risk of developing cardiac issues that are not currently present but may emerge as the child grows. This potential for evolving clinical manifestations necessitates vigilant long-term monitoring and may influence future medical management and therapeutic approaches.
A novel frameshift TBX4 variant in a family with ischio-coxo-podo-patellar syndrome and variable severity.
Congenital anomalies of the knee are a spectrum of rare disorders with wide clinical and genetic variability, which are mainly due to the complex processes underlying knee development. Despite progresses in understanding pathomechanisms and associated genes, many patients remain undiagnosed. To uncover the genetic bases of a congenital patellar dislocation affecting multiple family members with variable severity. We performed ES in the proband and his father, both showing bilateral patellar dislocation, his sister with a milder similar condition, and his unaffected mother. Sanger sequencing was then performed in the proband's brother and paternal aunt, both affected as well. ES and Sanger sequencing identified the presence of the novel heterozygous frameshift mutation c.735delT in the TBX4 gene in all affected family members. TBX4 is associated with autosomal dominant ischio-coxo-podo-patellar syndrome with/without pulmonary arterial hypertension (ICPPS, #147891), reaching a diagnosis in the family. Intrafamilial clinical heterogeneity suggests that other factors might be involved, such as additional variants in TBX4 or in other modifier genes. Interestingly, we identified three additional variants in the TBX4 gene in the proband only, whose phenotype is more severe. Despite being classified as benign, one of these variants is predicted to disrupt a splicing protein binding site, and may therefore affect TBX4 alternative splicing, accounting for the more severe phenotype of the proband. We expand and further delineate the genotypic and phenotypic spectrum of ICPPS. Further studies are necessary to shed light on the potential effect of this variant and on the variable phenotypic expressivity of TBX4-related phenotypes.
