Expanding the clinical spectrum of hereditary fibrosing poikiloderma with tendon contractures, myopathy and pulmonary fibrosis due to FAM111B mutatio…
2015
Background Hereditary Fibrosing Poikiloderma (HFP) with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP [MIM 615704]) is a very recently described entity of syndromic inherited poikiloderma. Previously by using whole exome sequencing in five families, we identified the causative gene, FAM111B (NM_198947.3), the function of which is still unknown. Our objective in this study was to better define the specific features of POIKTMP through a larger series of patients. Methods Clinical and molecular data of two families and eight independent sporadic cases, including six new cases, were collected. Results Key features consist of: (i) early-onset poikiloderma, hypotrichosis and hypoh…
Lymphoproliferative disorders in Sotos syndrome: Observation of two cases
1996
Sotos syndrome is included among the overgrowth disorders, most of which have an increased risk of neoplasms. Sotos syndrome does not appear to be related to a specific tumor type, but rather to the development of solid tumors of ectodermal or mesodermal origin in general. We report on two Sotos syndrome patients who developed a non-Hodgkin lymphoma and an acute lymphoblastic leukaemia, respectively. Our experience suggests that there may exist a high frequency of lymphoproliferative disorders in Sotos syndrome, and points out the importance of a long-term follow-up of Sotos syndrome patients, to detect a possible neoplastic evolution. ©1996 Wiley-Liss, Inc.
Spondylo-costal dysostosis in two siblings
1992
Two new cases of Spondylo-Costal Dysostosis (SCD) are reported in two siblings with strikingly similar skeletal abnormalities. Parental consanguinity documents in this family an autosomal recessive inheritance of trait. Clinical variability of SCD is discussed on the basis of clinical and radiological features. Its genetic heterogeneity is pointed out even considering the occurrence of cases with autosomal dominant as well as recessive inheritance.
Familial thoracic aortic aneurysm/dissection with patent ductus arteriosus: genetic arguments for a particular pathophysiological entity.
2004
International audience; Thoracic aortic aneurysm and aortic dissection (TAA and AD) are an important cause of sudden death. Familial cases could account for 20% of all cases. A genetic heterogeneity with two identified genes (FBN1 and COL3A1) and three loci (3p24-25 or MFS2/TAAD2, 5q13-q14 and 11q23.2-24) has been shown previously. Study of a single family composed of 179 members with an abnormally high occurrence of TAA/AD disease. A total of 40 subjects from three generations were investigated. In addition to five cases of stroke and three cases of sudden death, there were four cases of AD and four cases of TAA in adults. In all, 11 cases of patent ductus arteriosus (PDA) were observed, t…
Further delineation of eye manifestations in homozygous 15q13.3 microdeletions including TRPM1: a differential diagnosis of ceroid lipofuscinosis.
2014
The 15q13.3 heterozygous microdeletion is a fairly common microdeletion syndrome with marked clinical variability and incomplete penetrance. The average size of the deletion, which comprises six genes including CHRNA7, is 1.5 Mb. CHRNA7 has been identified as the gene responsible for the neurological phenotype in this microdeletion syndrome. Only seven patients with a homozygous microdeletion that includes at least CHRNA7, and is inherited from both parents have been described in the literature. The aim of this study was to further describe the distinctive eye manifestations from the analysis in the three French patients diagnosed with the classical 1.5 Mb homozygous microdeletion. Patients…
Clinical features and follow-up in patients with 22q11.2 deletion syndrome
2014
Objective To investigate the clinical manifestations at diagnosis and during follow-up in patients with 22q11.2 deletion syndrome to better define the natural history of the disease. Study design A retrospective and prospective multicenter study was conducted with 228 patients in the context of the Italian Network for Primary Immunodeficiencies. Clinical diagnosis was confirmed by cytogenetic or molecular analysis. Results The cohort consisted of 112 males and 116 females; median age at diagnosis was 4 months (range 0 to 36 years 10 months). The diagnosis was made before 2 years of age in 71% of patients, predominantly related to the presence of heart anomalies and neonatal hypocalcemia. In…
Etiological heterogeneity and clinical variability in newborns with esophageal atresia
2018
Abstract Background The aim of this study was to define different characteristics of infants with esophageal atresia and correlations with neonatal level of care, morbidity and mortality occurring during hospital stay. Methods Charts of all newborns with esophageal atresia (EA) admitted to our University NICU between January 2003 and November 2016 were reviewed and subdivided in four groups related to different clinical presentations; EA as an isolated form (A), with a concomitant single malformation (B), as VACTERL association (C), and in the context of a syndrome or an entity of multiple congenital anomalies (D). Results We recruited 67 infants with EA (with or without tracheoesophageal f…
Kawasaki disease: guidelines of the Italian Society of Pediatrics, part I - definition, epidemiology, etiopathogenesis, clinical expression and manag…
2018
Abstract The primary purpose of these practical guidelines related to Kawasaki disease (KD) is to contribute to prompt diagnosis and appropriate treatment on the basis of different specialists’ contributions in the field. A set of 40 recommendations is provided, divided in two parts: the first describes the definition of KD, its epidemiology, etiopathogenetic hints, presentation, clinical course and general management, including treatment of the acute phase, through specific 23 recommendations. Their application is aimed at improving the rate of treatment with intravenous immunoglobulin and the overall potential development of coronary artery abnormalities in KD. Guidelines, however, should…
Clinical and genetic approach in the characterization of newborns with anorectal malformation
2022
Objective: This study aimed to investigate clinical, surgical, and genetic data of neonates with anorectal malformation (ARM). Study design: A retrospective observational study was conducted on neonates with ARM as an isolated type (group 1), with ≤2 (group 2), and with ≥3 associated malformations (group 3), born between 2009 and 2020. Distribution of ARM, associated abnormalities and genetic testing were analyzed, and risk factors for adverse outcomes were identified. Results: The 45 ARM cases (36% females) were divided as follows: 13 neonates belonging to group 1 (29%), 8 to group 2 (18%), and 24 to group 3 (53%). Cases were equally distributed over 11 years. Krickenbeck anatomy was: with…
Skeletal abnormalities of the upper limbs--neonatal diagnosis of 49,XXXXY syndrome.
2012
A case of neonatal diagnosis of 49,XXXXY syndrome is presented. Clinical identification was prompted by a bilateral thickening of the radioulnar joints and X-ray imaging disclosing almost complete radioulnar synostosis. Conventional karyotyping was initiated and revealed a karyotype of 49,XXXXY. Previously reported neonatal symptoms such as low birth weight, muscular hypotonia, or genital malformations were absent in this case. Microsatellite analysis showed two different X chromosomes each present in two copies, supporting that the four X chromosomes had arisen from a nondisjunction in maternal meiosis I followed by a second nondisjunction involving both X chromosomes in meiosis II. Multid…
