Prenatal Tympanic Ring Anomaly Without Microtia: A Subtle Clue Toward Severe Early‐Onset Monogenic Disorders

Prenatal Diagnosis, Volume 46, Issue 7, Page 1096-1103, June 2026.
ABSTRACT Objective To investigate the genetic etiologies and clinical significance of fetal tympanic ring abnormalities detected during second‐trimester ultrasound in the absence of microtia. Method Between November 2019 and June 2024, we examined the fetal tympanic rings of 10,277 unselected pregnant women during the 20–22 weeks of morphology ...

The transcription of the main gene associated with Treacher–Collins syndrome (TCOF1) is regulated by G-quadruplexes and cellular nucleic acid binding protein (CNBP)

Scientific Reports
Treacle ribosome biogenesis factor 1 (TCOF1) is responsible for about 80% of mandibular dysostosis (MD) cases. We have formerly identified a correlation between TCOF1 and CNBP (CCHC-type zinc finger nucleic acid binding protein) expression in human ...

Co‐occurrence of orofacial clefts and clubfoot phenotypes in a sub‐Saharan African cohort: Whole‐exome sequencing implicates multiple syndromes and genes

Molecular Genetics & Genomic Medicine, 2021
Background Orofacial clefts (OFCs) are congenital malformations of the face and palate, with an incidence of 1 per 700 live births. Clubfoot or congenital talipes equinovarus (CTEV) is a three‐dimensional abnormality of the leg, ankle, and feet that ...

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Prevention of Treacher Collins syndrome craniofacial anomalies in mouse models via maternal antioxidant supplementation

Nature Communications, 2016
The TCOF1 gene is mutated in Treacher Collin's syndrome, a congenital craniofacial syndrome. Here, the authors show that Tcof1loss-of-function results in oxidative stress induced DNA damage and neuroepithelial cell death, and addition of antioxidants to ...

Implementation of an Inherited Diseases Gene Panel to Accelerate Precision Medicine in the South African Public Healthcare System

Molecular Genetics &Genomic Medicine, Volume 14, Issue 4, April 2026.
We developed and implemented a 500‐gene panel for phenotype‐driven genetic testing of Mendelian disorders in South Africa's public healthcare system, achieving a 46% diagnostic yield. This platform supports scalable, cost‐effective rare disease diagnosis and lays the foundation for broader genetic services in resource‐limited settings.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

FEBS Open Bio, Volume 16, Issue 3, Page 561-569, March 2026.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Targeted Next-Generation Sequencing in the Diagnosis of Facial Dysostoses

Frontiers in Genetics, 2020
BackgroundDefects in the development of the first and second pharyngeal arches and their derivatives result in abnormal formation of the craniofacial complex, consequently giving rise to facial dysostoses (FDs).

Genetic Landscape of Robin Sequence: A Systematic Review

Clinical Genetics, Volume 109, Issue 2, Page 218-232, February 2026.
This systematic review summarizes the genetic landscape of Robin sequence (RS), highlighting key differences between isolated and non‐isolated forms and emphasizing the role of up‐to‐date genetic testing for diagnosis and clinical management. ABSTRACT Robin sequence (RS) is a congenital condition characterized by micrognathia, glossoptosis, and upper ...
