Oculoauriculovertebral Spectrum

Kaufman oculocerebrofacial syndrome is a rare autosomal recessive disorder which represents a phenotype mainly involving craniofacial and neurodevelopmental manifestations due to <i>UBE3B</i> gene mutations. The vast majority of the affected individuals exhibit microcephaly, eye abnormalities, and typical facial gestalt including blepharophimosis, ptosis, telecanthus, upslanting palpebral fissures, dysplastic ears, and micrognathia. We encountered 2 siblings in whom severe psychomotor delay, distinctive facial features, hearing loss, and respiratory distress were observed. Some clinical manifestations of the patients, including epibulbar dermoid, microtia, and multiple preauricular tags, were reminiscent of the oculoauriculovertebral spectrum. However, 2 affected siblings exhibited a similar clinical picture consisting of microcephaly, severe developmental and cognitive disabilities, failure to thrive, and dysmorphic features, which were not fully consistent with oculoauriculovertebral spectrum. Also, hypoplastic nails, considered as a core manifestation of Coffin-Siris syndrome, were present in our patients. Therefore, whole-exome sequencing was carried out in order to identify the underlying genetic alterations, contributing to the complex phenotype shared by the 2 siblings. A homozygous pathogenic mutation was found in both affected siblings in the <i>UBE3B</i> gene which caused Kaufman oculocerebrofacial syndrome. Kaufman oculocerebrofacial syndrome should be considered among the autosomal recessive causes of blepharophimosis-mental retardation syndromes, particularly in populations with a high rate of consanguineous marriages, even if there are dysmorphic facial features that are not typically associated with the phenotype.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder associated with rapidly progressing periodontitis leading to premature loss of deciduous and permanent dentition and diffuse palmoplantar keratosis. Immunologic alterations, genetic mutations, and role of bacteria are some aetiologic factors. Patients present with early periodontal destruction, so periodontists play a significant role in diagnosis and management. This paper reports a case of Papillon- Lefevre syndrome with its clinical manifestations and challenges for periodontal management which was diagnosed in dental department.

Abstract Ellis-van Creveld (EVC) syndrome or chondroectodermal dysplasia is a rare autosomal recessive disorder characterized by a variable spectrum of clinical findings. Classical EVC syndrome comprises a tetrad of clinical manifestations of chondrodystrophy, polydactyly, ectodermal dysplasia, and cardiac defects. In several case reports, dysplasia involving other organs has also been identified. Hematologic abnormalities have been rarely reported in patients with EVC syndrome. Here, we report a case of a 3-year-old Hispanic boy with EVC syndrome and marked dyserythropoiesis. The dyserythropoiesis may be part of an isolated myelodysplastic change or a primary myelodysplastic syndrome and likely represents an unusual EVC syndrome association. To our knowledge, this association has not been previously reported.

Abstract Background 17α-hydroxylase deficiency is a rare autosomal recessive disorder caused by mutations in the cytochrome P450 family 17 subfamily A member 1 gene. The major clinical presentation includes hypertension, hypokalemia, male pseudohermaphroditism and female gonadal dysplasia. Hundreds of pathogenic variants have been reported in this disorder, and some common mutations were found to be race-specific. Case presentation In this study, we reported 5 Chinese girls with 17α-hydroxylase deficiency from Henan Province. The patients all came to the hospital for hypertension, and they also presented with sexual infantilism. The average age of the patients was 14 years old, ranging from 12 to 17 years old. They all had reduced blood cortisol, estradiol (E2), and testosterone (TESTO) and increased adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). They all had the appearance of females; however, three of the chromosome karyotypes were 46XX, and two were 46XY. Conclusions All of the patients carried a mutation on the 329 amino acid of CYP17A1 exon 6. By summarizing the currently known pathogenic mutations of 17α-hydroxylase deficiency, we demonstrated the prevalence of these gene mutations in Chinese Han and non-Chinese populations.

21 Hydroxylase Deficiency

11β-hydroxylase deficiency is a rare autosomal recessive disorder due to impaired steroidogenesis in the adrenal cortex caused by pathogenic mutations in the CYP11B1 gene. The main clinical manifestations are determined by a deficiency of cortisol, ACTH hyperproduction, excessive androgens secretion and the accumulation of 11-deoxycorticosterone, which leads to the development of arterial hypertension. In the diagnostic search, it is important to take into account the ethnicity of the patient, since the frequency of the disease and the prevalence of mutations differ between ethnic groups. The article presents a clinical case of 11β-hydroxylase deficiency as the result of compound heterozygous mutations in the CYP11B1 gene in a patient of Turkic origin. This case shows the clinical manifestations and the development of complications of 11β-hydroxylase deficiency, the stages of differential diagnosis of patients with 21-hydroxylase deficiency.

Published Research

Alkaptonuria (AKU) is a rare autosomal recessive disorder with a global incidence of 1 in 250 000 to 1 million people worldwide. It results from a deficiency of the enzyme homogentisic acid (HGA) oxidase which when absent, leads to an accumulation of HGA. Without this enzymatic degradation, HGA deposits in connective tissues resulting in pigmentation (ochronosis), plaque formation and accelerated cartilage destruction. With this, many patients who suffer from AKU develop ochronotic arthropathies, tendon ruptures, fractures, and chronic joint pain. Similarly, patients can develop cardiac valvular dysfunction and interstitial renal disease. Our two cases highlight the array of pathologies seen in AKU and, in light of newly published research, give us a platform from which we can discuss the developments in management of this rare disease.

Sensenbrenner Syndrome

Sensenbrenner syndrome is a very rare autosomal recessive disorder caused by variants in genes involved in the functional development of primary cilia. Typical clinical manifestations include craniofacial and skeletal abnormalities, hence the alternative name cranioectodermal dysplasia. Chronic kidney disease due to progressive tubulointerstitial nephritis (nephronophthisis) has been described in these patients. The authors present 2siblings with severe anorexia, failure to thrive, chronic kidney disease, and angel-shaped middle phalanges. Two previously described variants p.(Leu641*) and p.(Asp841Val) were identified in the <i>WDR35</i> gene which is most commonly affected in this condition. Analysis of all coding exons of the <i>GDF5</i> gene was normal. This is the first report of Sensenbrenner syndrome presenting with severe anorexia and failure to thrive at early age. Angel-shaped middle phalanges in the absence of the <i>GDF5</i> variant may represent an overlapping phenotypic manifestation of ciliopathy.

Rare Metabolic Disorder

Non-ketotic hyperglycinemia (NKH) is a rare autosomal recessive disorder affecting glycine metabolism that is a rare metabolic disorder in infants. The clinical manifestations of poor sucking, hypotonicity, lethargy, hiccups, and seizures develop within six hours to eight days of the birth of an otherwise healthy newborn. The present study introduced a newborn girl with poor feeding and hypotonia in the first day after birth with NKH. In addition, the patient was evaluated regarding hypotonia and poor feeding. The neonatal-onset NKH was diagnosed based on a markedly elevated cerebrospinal fluid/plasma glycine ratio of 0.32 and confirmed by the genetic test. It is extremely rare that NKH is manifested with poor feeding and hypotonia thus considering this diagnosis in infants with poor feeding and hypotonia is highly important.

Wilson’s disease is an autosomal recessive disorder caused by mutations in the ATP7B gene, a membrane-bound copper-transporting ATPase. Clinical manifestations are caused by copper toxicity and primarily involve the liver, the brain and the eye. Because effective treatment is available, it is important to make this diagnosis early. We report a patient who developed features of neurological and ocular manifestations: incoordination and tremor and blurring of vision with presence of Kayser-Fleischer ring circling the cornea but no signs of hepatic dysfunction.
