- Branchio-oto-renal (BOR) syndrome is a rare autosomal dominant disorder caused by pathogenic variants in , , or , which affect the branchial arches, auditory system, and kidneys. Diagnosis integrates clinical criteria that require major criteria such as branchial anomalies, hearing loss, or preauricular pits, as supported by genetic testing. Gene-targeted testing confirms typical BOR syndrome phenotypes, whereas comprehensive genomic testing identifies atypical cases. Management is tailored to the individual phenotypes. Kidney anomalies, the most important prognostic factor, necessitate early nephrology referral and interventions such as pyeloplasty for ureteropelvic junction obstruction or kidney replacement therapy for kidney failure. Hearing loss is addressed using hearing aids, surgical correction, or cochlear implantation, depending on the type and severity of hearing loss. Branchial anomalies, including cysts and sinuses, can be managed conservatively or surgically when symptomatic. Genetic counseling plays a critical role, given the 50% inheritance risk and the implications for family planning. Prenatal ultrasonography is recommended for detecting renal anomalies during at-risk pregnancies. Management of BOR syndrome requires a multidisciplinary approach that integrates otolaryngology, nephrology, and genetics. Advances in genomic technologies and a deeper understanding of phenotypic variability are essential for improving the outcomes of patients with BOR. - Source: PubMed

Kumarasamy GuhanPark Se JinPark Peong GangMoon In SeokShin Jae Il - : Branchio-oto syndrome (BOS) is an autosomal dominant disorder primarily associated with pathogenic variants in , mainly characterized by branchial anomalies, auricular abnormalities, and hearing loss. However, the co-occurrence of inner ear malformations in BOS remains understudied, especially severe malformations. This study aimed to investigate the clinical and genetic characteristics of patients with -associated BOS, with emphasis on cochlear nerve deficiency (CND). : From January 2020 to April 2026, patients diagnosed with -associated BOS at an otology outpatient clinic in a tertiary hospital were included. Clinical manifestations, audiological assessments, imaging and genetic findings were analyzed. : Thirteen patients (six females and seven males) from eight unrelated families aged 0.3-58.3 years were enrolled. Branchial cleft fistulas and preauricular pits were each observed in 76.9% (10/13) of patients. The mean pure-tone average was 74.3 ± 20.7 dB HL. Eight variants (four truncating, two large deletions, and two splicing) were identified. Among these, five were novel (c.320_329del, c.518del, c.1307dupT, c.1475+1G>A, and exon 12-18 deletion). CND was detected in 38.5% (5/13) of patients and 26.9% (7/26) of ears. Patients with CND carried either truncating variants ( = 3) or large deletions ( = 2) of . No CND was observed in patients with splicing variants. : This study identifies five novel pathogenic variants and suggests that CND may be a relatively common radiologic feature in -associated BOS, particularly among patients with truncating variants or large deletions, although larger studies are needed to confirm this association. - Source: PubMed

Niu YirongLin YunYu JialiZhao HuanhuanZhao YutingChen JieSun YingAn ZeqiWang MengpingHan KunWu HaoLi YunWang ZhiliChen Ying - Branchio-oto-renal (BOR) syndrome is an autosomal dominant condition characterized by variable malformations including hearing loss and renal dysfunction. Variants in SIX1 or its activating co-factor EYA1 are causative in about 50% of patients. Some patients carrying BOR variants also present with craniosynostosis, indicating that cranial skeletal dysmorphologies could be an under-diagnosed feature. To date, most studies on the role of SIX1 have focused on its role in the cranial placode-based development of the inner ear, whereas its role in the neural crest cells of the mandibular arch, which will give rise to the jaws and middle ear ossicles, is less well characterized. Here, we present novel expression profiles of three putative SIX1 co-factors (PA2G4, MCRS1, and SOBP) in the developing mouse first pharyngeal arch and tooth. SIX1 colocalizes with PA2G4, MCRS1, and SOBP within the oral domain of the mandibular arch and during odontogenesis, although each exhibits a distinct expression pattern. Functional analyses revealed that SOBP binds SIX1, EYA1, and EYA2 and represses both SIX1 + EYA1 and SIX1 + EYA2 transcriptional activity, whereas MCRS1 binds only SIX1 and selectively represses SIX1 + EYA2 activity. In contrast, PA2G4 does not bind SIX1, yet modulates SIX1 + EYA2 activity. We further show that SIX1 is required for proper expression of Pa2g4, Mcrs1, and Sobp in the mouse mandibular arch. Collectively, these results demonstrate that regulation of SIX1 + EYA transcriptional activity is highly context dependent, occurs through both direct and indirect mechanisms, and differs between SIX1 + EYA1 and SIX1 + EYA2 complexes. These findings reveal species-specific differences and uncover a level of regulatory complexity not previously identified in Xenopus studies. - Source: PubMed

Jourdeuil KarynChukwuocha KelechiGafurova JasminaBen-Mayor AshleyMoody Sally ATavares Andre L P - Osteoarthritis (OA) involves progressive extracellular matrix (ECM) degradation in articular cartilage. We previously revealed that the mA demethylase ALKBH5 stabilizes Runx2 mRNA in chondrocytes via YTHDF1, thereby increasing MMP and ADAMTS expression, causing ECM degradation. However, the transcriptional co-regulators of Runx2 remain unidentified. - Source: PubMed

Nie GuanghuaLi YiZhao HongmouWang DongZhang YanYang XinquanWen Xiaodong - Ménière disease (MD) is a chronic inner ear disorder characterized by recurrent vertigo, fluctuating sensorineural hearing loss, and tinnitus, but its etiology remains poorly understood. We performed a genome-wide meta-analysis of 8,969 MD case subjects and 1,962,542 control subjects across five biobanks, identifying five independent genome-wide significant loci and estimating an observed-scale SNP heritability of 7% (SE 0.8%), indicating a modest but significant contribution of common genetic variation to MD risk. The genome-wide significant signals comprise two independent variants at EYA4, two at EYA1, and one near CYP26A1, with odds ratios between 1.1 and 1.25. Associations at two additional loci, LMO4 and ALDH1A2, fell just below the genome-wide significance threshold (5 × 10 Publication date: 2026/06/16
