Abernethy malformation associated with Caroli's syndrome in a patient with a PKHD1 mutation: a case report.

ABSTRACT: Abernethy malformation is a rare congenital anomaly characterised by the partial or complete absence of the portal vein and the subsequent development of an extrahepatic portosystemic shunt. Caroli's disease is a rare congenital condition characterised by non-obstructive saccular intrahepatic bile duct dilation. Caroli's disease combined with congenital hepatic fibrosis and/or renal cystic disease is referred to - Caroli's syndrome. The combination of Abernethy malformation and Caroli's syndrome has not been reported previously.We present the case of a 23-year-old female who was found to have both type II Abernethy malformation and Caroli's syndrome. Radiological imaging was performed, including computed tomography with three-dimensional reconstruction and magnetic resonance imaging with (magnetic resonance cholangiopancreatography (MRCP), which revealed a side-to-side portocaval shunt, intrahepatic bile duct dilation, congenital hepatic fibrosis, and renal cysts. In addition, PKHD1 (polycystic kidney and hepatic disease 1) gene mutational analysis revealed a paternally inherited heterozygous missense mutation (c.1877A > G, p.Lys626Arg). A liver biopsy confirmed the pathological features of Caroli's syndrome.To our knowledge, this is the first reported case of a patient with both type II Abernethy malformation and Caroli's syndrome diagnosed using a comprehensive approach that included imaging, mutational analysis, and liver biopsy. Additionally, this is the second reported case to date of an Asian patient presenting with liver and renal disorders with the same paternally inherited PKHD1 missense mutation.

A Novel Frameshift Mutation Associated with Hurler's Syndrome: A Case Report.

Project description:Mucopolysaccharidosis 1 (MPS1) is a rare inherited lysosomal storage disorder resulting from the absence or reduction of lysosomal alpha-l-iduronidase due to mutations in the IDUA gene. Three major clinical manifestations have been established including Hurler's or severe type (OMIM 607914), Hurler-Scheie or intermediate type (MIM 607914) and Scheie's or attenuated type (MIM 607016). In the present study, a patient whose disease was diagnosed by biochemical and enzymatic assay was studied in our laboratory. Molecular analysis implemented by PCR-sequencing of all 14 exons and exon-intron junctions confirmed a novel deleterious mutation in a homozygous state. The result of this study has broadened the genotypic spectrum of MPS1 patients, assisting in a more effective approach for carrier testing and counseling.

Case report: Progressive pulmonary artery hypertension in a case of megalencephaly-capillary malformation syndrome.

Project description:Megalencephaly-capillary malformation syndrome (MCAP, OMIM # 602501) is caused by hyperactivity of the thephosphoinositide-3-kinase (PI3K)-Vakt murine thymoma viral oncogene homolog (AKT)-mammalian target of rapamycin (mTOR) pathway, which results in megalencephaly, capillary malformations, asymmetrical overgrowth, and connective tissue dysplasia. Herein, we report the case of a 7-month-old girl with MCAP due to a PIK3CA somatic mosaic variant who presented with atrial tachycardia, finally diagnosed as pulmonary arterial hypertension (PAH). Oxygen therapy and sildenafil decreased pulmonary blood pressure and improved atrial tachycardia. Previous studies reported an association between the PI3K/AKT/mTOR pathway and abnormal pulmonary arterial smooth muscle cell proliferation, which may be associated with PAH. PAH should be considered a potentially lethal complication in MCAP patients, even when no structural cardiac abnormalities are identified in the neonatal period.

Tetralogy of Fallot associated with macrocephaly-capillary malformation syndrome: a case report and review of the literature.

Project description:IntroductionMacrocephaly-capillary malformation syndrome is characterized by cutaneous vascular lesions, including cutis marmorata telangiectatica and hemangiomas, associated with congenital anomalies, including macrocephaly, macrosomia, asymmetry and mental retardation. In addition to these cardinal signs, several other clinical conditions have been reported in people with this condition. However, to the best of our knowledge, the presence of tetralogy of Fallot has not previously been reported in association with this syndrome.Case presentationWe present a case of a Mexican newborn girl with tetralogy of Fallot associated with macrocephaly-capillary malformation. We discuss the clinical treatment of the patient and its consequences.ConclusionSince physiologic cutis marmorata is a common condition in newborns, the information provided in this report could be helpful in future cases in preventing severe clinical consequences or sudden death in patients with similar symptoms.

A Missense Mutation in LMX1A in a Patient With Moebius Syndrome: A Case Report.

Project description:Moebius syndrome is characterized by congenital complete or partial paralysis of the facial nerve and is often associated with orofacial and limb malformations. It is a rare syndrome that affects the sixth and seventh cranial nerves. Facial paralysis results in abnormal abduction of one or both eyes and facial paralysis or weakness. Moebius syndrome is an uncommon condition and only a few hundred cases have been reported in the literature. A seven-year-old girl with Moebius syndrome is featured in this report. She had asymmetrical facial expressions, ocular abduction anomalies, and swallowing difficulties. She also had mild low-set ears, hypertelorism, a short nose, and restricted jaw movements. Array-comparative genomic hybridization analysis of exosome sequencing showed a mutation p.Gln61Arg in exon 3 of LMX1A.

A First Case Report of Subependymoma in PTPN11 Mutation-Associated Noonan Syndrome.

Project description:Noonan syndrome (NS) is an autosomal dominant disorder in some cases caused by PTPN11 mutations. Since somatic mutations in PTPN11 are seen in several tumor types, NS which causes germline PTPN11 mutations are also increase the risk of hematologic malignancies and brain solid tumors. However, the report of brain tumors in Noonan syndrome remains rather rare. Here, we report the first case of an 11-year-old Thai boy with Noonan syndrome who presented with symptoms related to hydrocephalus secondary to subependymoma in the fourth ventricle, and PTPN11 mutation was identified in this patient.

A novel familial mutation associated with Treacher Collins syndrome: A case report.

Project description:Treacher Collins syndrome (TCS) is a type of mandibulofacial dysostosis with incomplete penetrance and high intra- and interfamilial clinical heterogeneity, and it is associated with mutations of treacle ribosome biogenesis factor 1 (TCOF1), and RNA polymerase I and III subunit (POLR1)C and POLR1D genes. In the present case report, a patient with TCS with auricle dysplasia and hearing loss accompanied with intellectual disability is described. Sequence analysis was performed on blood samples from the patient and his father via oligonucleotide-based target capture, followed by next-generation sequencing. Alignment and variant calls were generated using the Burrows-Wheeler Aligner and Genome Analysis Toolkit, followed by bioinformatics analysis of the detected variants. A novel heterozygous mutation, c.911C>T (p.Ser304Leu), was detected in the TCOF1 gene, which was inherited from the father. The father of the patient only suffered from hearing loss. The present report is the first to identify an association between phenotypic variability and TCOF1 gene mutations and thus contributes to our understanding of the association between the genotype and phenotype in patients with TCS and offers clinically relevant information for diagnosis of the syndrome.

Obstructive shock in pediatric patient with congenital cystic adenomatoid malformation: A case report.

Project description:Introductionand importance: Congenital cystic adenomatoid malformation (CCAM) is a rare cystic lesion in the lungs. CCAM might present in the early neonatal period with symptoms of respiratory distress.Case presentationA 2-year-old girl was admitted to our Pediatric Intensive Care Unit with signs of severe respiratory distress. She had been diagnosed with CCAM since she was three months old. She also had undergone several procedures such as thoracotomy and decortication since then, but she still suffered some episodes of pulmonary infection. In this admission, her computerized thoracic tomography revealed a pleuropulmonary blastoma (PPB).Clinical discussionAn obstruction of blood outflow from the left ventricle could happen when an intrathoracic mass exists, leading to a decrease of cardiac output and resulting in an obstructive shock, which could be fatal. One of the malignancy types commonly occurring is pleuropulmonary blastoma (PPB), which has a poor prognosis. Early detection on CCAM can be done by prenatal ultrasound.ConclusionObstructive shock is one of complication that might occur in pleuropulmonary blastoma.

Identification of KRAS mutation in a patient with linear nevus sebaceous syndrome: a case report.

Project description:BackgroundLinear nevus sebaceous syndrome (LNSS) is a rare genetic disease characterized by large linear sebaceous nevus typically on the face, scalp, or neck. LNSS could be accompanied by multisystem disorders including the central nervous system. Herein, we report gene mutational profile via whole exome sequencing of both lesional and non-lesional skin samples in a LNSS patient.Case presentationA 17-year-old girl presented with multisystem abnormalities, including large skin lesions, ocular disorders, abnormal bone development and neurological symptoms. A diagnosis of LNSS was established based on clinical manifestations, histopathological and imaging findings. The skin lesions were resected and no recurrence was noted at the time of drafting this report. Whole exome sequencing of genomic DNA revealed the following 3 mutations in the lesions of the index patient: KRAS (c.35G > A, p.G12D), PRKRIR (c.A1674T, p.R558S), and RRP7A (c. C670T, p.R224W), but no mutation was found in the healthy skin and peripheral blood sample of the index patient, or in the blood samples of her parents and sibling. PCR-mediated Sanger sequencing of DNA derived from lesional skin sample of the index patient verified KRAS mutation, but not PRKRIR (c.A1674T, p.R558S) and RRP7A (c. C670T, p.R224W). None of the 3 mutations was found in Sanger sequencing in skin lesions of 60 other cases of nevus sebaceous patients.ConclusionsOur findings show the relevance of KRAS mutation to LNSS, providing new clues in understanding related genetic heterogeneity which could aid genetic counselling for LNSS patients.
