Cervico-oculo-acoustic (Wildervanck) syndrome: clinicoradiological findings.

ABSTRACT: We describe a girl presented with facial asymmetry and oral mucosal cleft and with further investigations other anomalies were found including hearing loss, Duane syndrome, Klippel-Feil anomaly, Chiari malformation and accessory bone mass in mandibular ramus leading to the clinical diagnosis of cervico-oculo-acoustic (Wildervanck) syndrome (COAS). The patient underwent surgical occipital decompression by preforming suboccipital craniectomy and C1 posterior laminectomy to relieve the cerebellar tonsillar herniation. Surgical removal of mandibular bony mass was done and the patient is now under orthodontic treatment to correct facial asymmetry and malocclusion.

Prenatal findings of cataract and arthrogryposis: recurrence of cerebro-oculo-facio-skeletal syndrome and review of differential diagnosis.

Project description:BackgroundCerebro-oculo-facio-skeletal syndrome (COFS) is a severe and progressive neurologic condition characterized by prenatal onset of arthrogryposis, cataract, microcephaly and growth failure. The aim of this study was to present a case of recurrence of the COFS syndrome and to propose a differential diagnosis flow-chart in case of prenatal findings of arthrogryposis and cataract.Case presentationWe report a case of recurrence of COFS3 syndrome within the same family, with similar diagnostic features. In the first case the COFS syndrome remained undiagnosed, while in the second case, due to prenatal findings of arthrogryposis and cataract, genetic investigation focusing on responsible genes of COFS (ERCC5, ERCC6 and FKTN genes) was carried out. The fetus was found to be compound heterozygous for two different ERCC5 mutations, confirming the clinical suspect of COFS syndrome. A review of the literature on possible causative genes of prenatal cataract and arthrogryposis was performed and we present a flow-chart to guide differential diagnosis and possible genetic testing in case of these findings.ConclusionCOFS syndrome is a rare autosomic recessive condition. However, it can be suspected and diagnosed prenatally. The flow-chart illustrates a pathway to guide differential diagnosis according to the prenatal findings. Main syndromes, key testing and specific genes are included. Targeted molecular testing should be offered to the couple in order to reach a diagnosis and assess the recurrence risk for future pregnancies.

Case report: Two siblings with neuronal intranuclear inclusion disease exhibiting distinct clinicoradiological findings.

Project description:Neuronal intranuclear inclusion disease (NIID) is a rare neurodegenerative disorder characterized by the presence of eosinophilic hyaline intranuclear inclusions. Owing to its widely varying clinical manifestations, NIID is frequently misdiagnosed or overlooked. However, a characteristic high-intensity corticomedullary junction signal on diffusion-weighted imaging (DWI) is often indicative of NIID. In this study, we described the case of two sisters with NIID who presented with distinct symptoms and imaging data. The younger sister showed symptoms similar to those of mitochondrial encephalopathy, with a reversible high-intensity signal from the cortex on T2 and DWI. The elder sister showed a characteristic high-signal "ribbon sign" in the corticomedullary junction on DWI. Skin biopsy confirmed that both had neuronal intranuclear inclusion. Two years later, the younger sister also developed the characteristic high-signal "ribbon sign" in the corticomedullary junction on DWI. This case study provides new insights into the complexity of NIID. The findings suggest that patients with this condition, including those belonging to the same family, may exhibit varying clinical and imaging features at different times.

TFAP2A mutations result in branchio-oculo-facial syndrome.

Project description:Branchio-oculo-facial syndrome (BOFS) is a rare autosomal-dominant cleft palate-craniofacial disorder with variable expressivity. The major features include cutaneous anomalies (cervical, infra- and/or supra-auricular defects, often with dermal thymus), ocular anomalies, characteristic facial appearance (malformed pinnae, oral clefts), and, less commonly, renal and ectodermal (dental and hair) anomalies. The molecular basis for this disorder is heretofore unknown. We detected a 3.2 Mb deletion by 500K SNP microarray in an affected mother and son with BOFS at chromosome 6p24.3. Candidate genes in this region were selected for sequencing on the basis of their expression patterns and involvement in developmental pathways associated with the clinical findings of BOFS. Four additional BOFS patients were found to have de novo missense mutations in the highly conserved exons 4 and 5 (basic region of the DNA binding domain) of the TFAP2A gene in the candidate deleted region. We conclude BOFS is caused by mutations involving TFAP2A. More patients need to be studied to determine possible genetic heterogeneity and to establish whether there are genotype-phenotype correlations.

Oculo-facio-cardio-dental (OFCD) syndrome: a case report.

Project description:BackgroundOculo-facio-cardio-dental (OFCD) syndrome is a rare condition that affects the eyes, face, heart, and teeth of patients. One notable dental characteristic of OFCD is radiculomegaly, or root gigantism, which highlights the role of dentists in detecting this syndrome. OFCD is an X-linked dominant syndrome that results from a variant in the BCOR gene. Our study presents the first documented case of OFCD in Vietnam and reports a novel BCOR gene variant observed in this case.Case presentationA 19-year-old Vietnamese female patient with an extremely long root with an abscess was clinically examined for the expression of OFCDs. The radiograph and the variant in BCOR gene were also evaluated. We identified abnormalities in the teeth, as well as ocular, facial, and cardiac features, with radiculomegaly of the canines being a specific symptom for OFCDs. The patient's genetic analysis revealed a pathogenic heterozygous deletion at intron 11 of the BCOR gene, representing a novel variant.ConclusionOculo-facio-cardio-dental syndrome (OFCD) is an extremely rare condition characterized by abnormalities in the eyes, face, heart, and teeth, often caused by variants in the BCOR gene. Radiculomegaly, or enlarged dental roots, is a key diagnostic feature of OFCD, and early detection is crucial for preventing future dental complications.

Oculo-ectodermal syndrome: A case report and further delineation of the syndrome.

Project description:Oculo-ectodermal syndrome (OES - OMIM 600628), also known as Toriello Lacassie Droste syndrome, is a very rare condition, first described by Toriello et al., in 1993. OES has been proposed to be a mild variant of encephalocraniocutaneous lipomatosis (ECCL). It is characterized by aplasia cutis congenita (ACC), epibulbar dermoids, coarctation of the aorta, arachnoid cysts in the brain, seizure disorder, hyperpigmented nevi, non-ossifying fibromas and a predisposition to develop giant cell tumors of the jaw. There are few reported cases of OES worldwide but with no definite diagnostic criteria yet. We present a case in a child with unilateral hyperpigmented nevi and ACC on the scalp, ocular lesions (lipodermoid cysts and coloboma), temporal arachnoid cyst, spinal lipomatosis and aortic coarctation with the aim of enhancing the foundation to establish diagnostic criteria for this condition. It additionally serves as a teaching point to emphasize the importance of pursuing a definite diagnosis when faced with such a multisystem illness, to counsel patients and their parents regarding long term morbidity and overall prognosis.

BCOR-regulated genes in human oculo-facio-cardio-dental syndrome

Project description:Oculo-facio-cardio-dental syndrome (OFCD) is a rare genetic disorder characterized by teeth with extremely long roots (radiculomegaly), and craniofacial, eye and cardiac abnormalities. The mutation of the transcriptional co-repressor BCOR has been identified as being responsible for oculo-facio-cardio-dental (OFCD) syndrome. Mesenchymal stem cells (MSCs) is isolated from the root apical papilla of an OFCD patient. Gene expression profiling is performed and compared between mutant MSCs and wild type MSCs. Total RNA were extracted from normal MSCs (MSCWT) and mutant MSCs (MSCO).

Ear abnormalities in patients with oculo-auriculo-vertebral spectrum (Goldenhar syndrome).

Project description:UnlabelledOculo-auriculo-vertebral spectrum (OAVS) is a rare condition characterized by the involvement of the first branchial arches.PurposeTo investigate the ear abnormalities of a sample of patients with OAVS.Materials and methodsThe sample consisted of 12 patients with OAVS seen at the Clinical Genetics Unit, UFCSPA/CHSCPA. The study included only patients who underwent mastoid computed tomography and with normal karyotype. We performed a review of its clinical features, giving emphasis to the ear findings.ResultsNine patients were male, the ages ranged from 1 day to 17 years. Ear abnormalities were observed in all patients and involved the external (n = 12), middle (n = 10) and inner ear (n = 3). Microtia was the most frequent finding (n = 12). The most common abnormalities of the middle ear were: opacification (n = 2), displacement (n = 2) and malformation of the ossicular chain. Agenesis of the internal auditory canal (n = 2) was the most frequent alteration of the inner ear.ConclusionsEar abnormalities are variable in patients with OAVS and often there is no correlation between findings in the external, middle and inner ear. The evaluation of these structures is important in the management of individuals with OAVS.

Manitoba-oculo-tricho-anal (MOTA) syndrome is caused by mutations in FREM1.

Project description:Manitoba-oculo-tricho-anal (MOTA) syndrome is a rare condition defined by eyelid colobomas, cryptophthalmos and anophthalmia/microphthalmia, an aberrant hairline, a bifid or broad nasal tip, and gastrointestinal anomalies such as omphalocele and anal stenosis. Autosomal recessive inheritance had been assumed because of consanguinity in the Oji-Cre population of Manitoba and reports of affected siblings, but no locus or cytogenetic aberration had previously been described.This study shows that MOTA syndrome is caused by mutations in FREM1, a gene previously mutated in bifid nose, renal agenesis, and anorectal malformations (BNAR) syndrome. MOTA syndrome and BNAR syndrome can therefore be considered as part of a phenotypic spectrum that is similar to, but distinct from and less severe than, Fraser syndrome. Re-examination of Frem1(bat/bat) mutant mice found new evidence that Frem1 is involved in anal and craniofacial development, with anal prolapse, eyelid colobomas, telecanthus, a shortened snout and reduced philtral height present in the mutant mice, similar to the human phenotype in MOTA syndrome.The milder phenotypes associated with FREM1 deficiency in humans (MOTA syndrome and BNAR syndrome) compared to that resulting from FRAS1 and FREM2 loss of function (Fraser syndrome) are also consistent with the less severe phenotypes resulting from Frem1 loss of function in mice. Together, Fraser, BNAR and MOTA syndromes constitute a clinically overlapping group of FRAS-FREM complex diseases.

Novel TFAP2A mutation in a Japanese family with Branchio-oculo-facial syndrome.

Project description:Branchio-oculo-facial syndrome (BOFS) is a rare autosomal dominant disorder characterized by craniofacial, ocular, and ectodermal anomalies. BOFS is caused by mutation of the transcription factor AP2-alpha gene (TFAP2A). We performed detailed genetic analysis of a Japanese family with clinically suspected BOFS and identified a novel missense mutation resulting in a predicted amino-acid substitution in the highly conserved basic DNA-binding domain of TFAP2A (NM_003220.2:c.699A>C).
