Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: Autosomal dominant.
Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development (PubMed:12138111, PubMed:16357870, PubMed:30478443). DNA methylation is coordinated with methylation of histones (PubMed:12138111, PubMed:16357870, PubMed:30478443). It modifies DNA in a non-processive manner and also methylates non-CpG sites (PubMed:12138111, PubMed:16357870, PubMed:30478443).

Tatton-Brown-Rahman syndrome
An overgrowth syndrome characterized by a distinctive facial appearance, tall stature and intellectual disability. Facial gestalt is characterized by a round face, heavy horizontal eyebrows and narrow palpebral fissures. Less common features include atrial septal defects, seizures, umbilical hernia, and scoliosis.

Familial pneumothorax in twins with Tatton-Brown-Rahman DNMT3A overgrowth syndrome.
Spontaneous pneumothorax is a common respiratory presentation that may signal underlying genetic disease. Familial pneumothorax occurs in ~10% of primary cases, yet 75% remain genetically unclassified. We report identical twin brothers presenting with spontaneous pneumothoraces in adulthood, leading to a diagnosis of Tatton-Brown-Rahman syndrome (TBRS), a DNMT3A-related overgrowth disorder not previously associated with pneumothorax. Both individuals exhibited tall stature, mild intellectual disability, hypermobility, and cardiac abnormalities. Whole genome sequencing identified a rare de novo DNMT3A missense variant (c.1585 G > A, p.D529N) absent from population databases and predicted to be damaging. Methylation profiling confirmed genome-wide hypomethylation consistent with impaired DNMT3A function, supporting pathogenicity. No variants were found in known familial pneumothorax genes. Apical blebs observed at surgery and connective tissue features suggest a mechanistic link between TBRS and pneumothorax, analogous to other monogenic connective tissue disorders. This case expands the phenotypic spectrum of TBRS and highlights the importance of genetic evaluation in familial pneumothorax. Diagnosis enables personalised care, including surveillance for extrapulmonary complications such as aortic root dilatation and haematological malignancy. Our findings suggest that TBRS should be considered in patients presenting with pneumothorax, tall stature, and neurodevelopmental features. Further cases are needed to confirm this association and refine clinical management strategies.
Expanding the Malignancy Spectrum of Tatton-Brown-Rahman Syndrome: A Case of Hodgkin Lymphoma.
DNMT3A R882C variant in a patient with a presumed pineal gland tumor, highlighting potential tumor susceptibility in Tatton-Brown-Rahman syndrome.
Tatton-Brown-Rahman syndrome (TBRS) is a rare overgrowth disorder caused by germline alterations in DNMT3A, a gene essential for DNA methylation and epigenetic regulation. Affected individuals typically present with tall stature, intellectual disability, and neurodevelopmental disorders, and they also demonstrate an increased susceptibility to neoplastic disease. Reported tumors include hematologic malignancies, with acute myeloid leukemia being the most notable, as well as solid tumors such as neuroblastoma, medulloblastoma, benign glioma, and pituitary adenoma. Despite this expanding tumor spectrum, pineal gland tumors have not previously been described in association with TBRS. Here, we present the first known case of a presumed pineal gland tumor in a patient with TBRS. Although the lesion lacks histopathologic confirmation and a sporadic occurrence cannot be excluded, this observation raises the possibility that germline DNMT3A alterations may predispose to a broader range of tumors than previously recognized. This report underscores the need for continued documentation of unusual tumor presentations in TBRS to further elucidate the biology of DNMT3A-related tumorigenesis.

Tatton-Brown-Rahman Syndrome Due to a Novel DNMT3A Variant Presenting With Autism, Attention-Deficit/Hyperactivity Disorder (ADHD), and Regression: A Saudi Case Report.
Tatton-Brown-Rahman syndrome (TBRS) is a rare overgrowth/intellectual disability disorder caused by DNMT3A variants. It is characterized by tall stature, macrocephaly, and intellectual disability, with an expanding neuropsychiatric spectrum that includes autism spectrum disorder (ASD) and behavioral disturbances. We describe a young adult Saudi male with overgrowth, macrocephaly, coarse facial features, and global developmental delay. Cognitive testing confirmed mild intellectual disability with relative verbal strengths. He was diagnosed with ASD and attention-deficit/hyperactivity disorder (ADHD) and treated with methylphenidate in childhood. In early adulthood, the patient exhibited regression characterized by speech loss, decline in self-care, incontinence, and psychotic-like symptoms, alongside gastrointestinal disease. Genetic testing revealed a novel heterozygous DNMT3A missense variant (c.923G>T, p.Gly308Val) in the PWWP domain, consistent with TBRS. This case illustrates the broadened phenotype of TBRS, including ASD, ADHD, and regression, paralleling prior reports of cognitive unevenness and behavioral vulnerability. Additional findings of eczema, elevated IgE, and anemia suggest possible underrecognized systemic involvement. This case emphasizes the importance of multidisciplinary evaluation and lifelong neuropsychiatric follow-up in TBRS. As the first reported case from Saudi Arabia to our knowledge, it broadens the clinical and geographic spectrum of the disorder and highlights the association between DNMT3A variants, intellectual disability, and ASD.
