INTRODUCTION The clinical phenotype of the chromosome 2q31 deletion syndrome consists of limb anomalies ranging from monodactylous ectrodactyly, brachydactyly and syndactyly to camptodactyly. Additional internal organ anomalies-for example, heart defects, ocular anomalies-may be present. Hemizygosity for HOXD13 and EVX2 genes was thought to cause the observed skeletal defects. Recently, based o...
Congenital skeletal anomalies are rare disorders, with a subset affecting both the cranial and appendicular skeleton. Two categories, craniosynostosis syndromes and chondrodysplasias, frequently result from aberrant regulation of the fibroblast growth factor (FGF) signaling pathway. Our recent work has implicated FGF signaling in a third category: ciliopathic skeletal dysplasias. In this work, ...
Background and purpose: The prevalence of maxillary missing lateral incisor (MMLI) is 1-2% which is responsible for 20% of all missing teeth. Increased knowledge about causes and clinical manifestations of cases with this situation can be helpful for diagnosis and treatment planning. The aim of the present study was to determine dental and skeletal features of patients with missing maxillary la...
Introduction: Cornelia de lange syndrome(CDLS) is a rare syndrome which is characterized by multiple congenital anomalies, mental retardation, characteristic facial appearance, developmental delay, skeletal malformation, hirsutism, and various ophthalmologic problems. The diagnosis of this syndrome is clinical. Case Report: The patient of the present case report was an infant with cornelia ...
49,XXXXY is rare chromosomal pattern and these patients have mental retardation, small penis, cryptorchidism and skeletal anomalies. We reported a 10 month-old boy who has hypotonia, microcephaly, hypertelorism, depressed nasal bridge, epicanthic folds and bilateral multiple ear tags, high arched palate, down set ears, micrognathia and congenital heart disease such as patent ductus arteriosus (...
We present here the case of a 12-year-old boy who had Klippel-Feil syndrome with renal, cardiac and multiple skeletal anomalies, and we show the relevent three-dimensional computed tomography images. Our patient had a triple renal pelvis, mitral valve prolapsus, multiple cervical vertebrae fusions, cervical ribs, hypoplasia of the right thumb, spina bifida of L5, lumbalization at the right side...
Interstitial duplication within the long arm of chromosome 20 is an uncommon chromosome structural abnormality. We report here the clinical and molecular characterization associated with pure 20q13.2 duplication in three unrelated patients. The most frequent clinical features were developmental delay, facial dysmorphism, cardiac malformation and skeletal anomalies. All DNA gains occurred de nov...
Syrenomelia sequence is a rare (incidence of 1: 60000 births) [1,2] lethal pattern of congenital anomalies characterized by a number of hallmark skeletal anomalies including fusion of the lower extremities or a single lower limb, bilateral renal agenesis or dysgenesis with absent or hypoplastic renal arteries, oligohydramnios and the presence of aberrant vasculature. Prenatal sonographic detect...
The incidence of skeletal anomalies could be used as an indicator of the "quality" of rearing conditions as these anomalies are thought to result from the inability of homeostatic mechanisms to compensate for environmentally-induced stress and/or altered genetic factors. Identification of rearing conditions that lower the rate of anomalies can be an important step toward profitable aquaculture ...
