FGFR2 mediates extracellular signals into cells and the mutations in the FGFR2 gene cause this Molecular pathology syndrome occurrence. Activated FGFs/FGFR2 signaling disrupts the balance of differentiation, cell proliferation, Genetic phenotype and apoptosis via its downstream signal pathways. However, very little is known about the cellular and mole- cular factors leading to severity of this phenotype. Revealing the molecular pathology of craniosynostosis will be a great value for genetic counselling, diagnosis, prognosis and early intervention programs. This mini-review summarizes the fundamental and recent scientific literature on genetic disorder of Crouzon syndrome and presents a graduated strategy for the genetic approach, diagnosis and the management of this complex cra- niofacial defect. 1. Introduction known. CS commonly starts at the first three years of life.4 Craniosy- nostosis can be suspected during antenatal stage via ultrasound scan Craniosynostosis is a birth defect characterized by premature fusion otherwise is often detected at birth from its classic crouzonoid features of one or more of the calvarial sutures before the completion of brain of the newborn. -

Saethre-Chotzen Syndrome
Saethre-Chotzen syndrome Authors: Professor L. Clauser1 and Doctor M. Galié Creation Date: June 2002 Update: July 2004 Scientific Editor: Professor Raoul CM. Hennekam 1Department of craniomaxillofacial surgery, St. Anna Hospital and University, Corso Giovecca, 203, 44100 Ferrara, Italy. [email protected] Abstract Keywords Disease name and synonyms Excluded diseases Definition Prevalence Management including treatment Etiology Diagnostic methods Genetic counseling Antenatal diagnosis Unresolved questions References Abstract Saethre-Chotzen Syndrome (SCS) is an inherited craniosynostotic condition, with both premature fusion of cranial sutures (craniostenosis) and limb abnormalities. The most common clinical features, present in more than a third of patients, consist of coronal synostosis, brachycephaly, low frontal hairline, facial asymmetry, hypertelorism, broad halluces, and clinodactyly. The estimated birth incidence is 1/25,000 to 1/50,000 but because the phenotype can be very mild, the entity is likely to be underdiagnosed. SCS is inherited as an autosomal dominant trait with a high penetrance and variable expression. The TWIST gene located at chromosome 7p21-p22, is responsible for SCS and encodes a transcription factor regulating head mesenchyme cell development during cranial tube formation. Some patients with an overlapping SCS phenotype have mutations in the FGFR3 (fibroblast growth factor receptor 3) gene; especially the Pro250Arg mutation in FGFR3 (Muenke syndrome) can resemble SCS to a great extent.

Medical Center Drive (734) 763-6561 (fax) D5240 MPB Ann Arbor, MI 48109-5718 Biochemical Genetics Goals and Objectives Director: Drs. Ayesha Ahmad and Shane C. Quinonez The goals and objectives of the Biochemical Genetics Clinic rotation in the Medical Genetics Residency Program are to provide the resident with exposure to all aspects of care of metabolic disease and counseling in accordance with the Residency Review Committee for Medical Genetics expectations and to fulfill criteria for board eligibility by the American Board of Medical Genetics. Patient Care The resident will become familiar with the evaluation, diagnosis and management of urea cycle disorders, organic acidemias, disorders of carbohydrate and lipid metabolism and numerous other inborn errors of metabolism (IEMs). Residents will gain exposure in performing and expertise in interpreting biochemical analyses relevant to the diagnosis and management of human genetic diseases. By the end of the rotation the resident should be able to identify signs and symptoms of IEMs, formulate a differential diagnosis, order appropriate tests and recognize normal variants and complex patterns of metabolites. Residents will be able to manage acute metabolic crises and provide chronic management of patients with an IEM. Residents should be able to interpret NBS results, collaborate with the primary provider to act upon results in a timely manner, develop a differential diagnosis and order appropriate confirmatory testing and communicate results to families. Medical Knowledge Through coursework and didactic sessions with attending physicians, residents will become familiar with fundamental concepts, molecular biology and biochemistry relevant to IEMs. -

Blueprint Genetics Craniosynostosis Panel
Craniosynostosis Panel Test code: MA2901 Is a 38 gene panel that includes assessment of non-coding variants. Is ideal for patients with craniosynostosis. About Craniosynostosis Craniosynostosis is defined as the premature fusion of one or more cranial sutures leading to secondary distortion of skull shape. It may result from a primary defect of ossification (primary craniosynostosis) or, more commonly, from a failure of brain growth (secondary craniosynostosis). Premature closure of the sutures (fibrous joints) causes the pressure inside of the head to increase and the skull or facial bones to change from a normal, symmetrical appearance resulting in skull deformities with a variable presentation. Craniosynostosis may occur in an isolated setting or as part of a syndrome with a variety of inheritance patterns and reccurrence risks. Craniosynostosis occurs in 1/2,200 live births.

Mackenzie's Mission Gene & Condition List
Mackenzie’s Mission Gene & Condition List What conditions are being screened for in Mackenzie’s Mission? Genetic carrier screening offered through this research study has been carefully developed. It is focused on providing people with information about their chance of having children with a severe genetic condition occurring in childhood. The screening is designed to provide genetic information that is relevant and useful, and to minimise uncertain and unclear information. How the conditions and genes are selected The Mackenzie’s Mission reproductive genetic carrier screen currently includes approximately 1300 genes which are associated with about 750 conditions. The reason there are fewer conditions than genes is that some genetic conditions can be caused by changes in more than one gene. The gene list is reviewed regularly. To select the conditions and genes to be screened, a committee comprised of experts in genetics and screening was established including: clinical geneticists, genetic scientists, a genetic pathologist, genetic counsellors, an ethicist and a parent of a child with a genetic condition. The following criteria were developed and are used to select the genes to be included: • Screening the gene is technically possible using currently available technology • The gene is known to cause a genetic condition • The condition affects people in childhood • The condition has a serious impact on a person’s quality of life and/or is life-limiting o For many of the conditions there is no treatment or the treatment is very burdensome for the child and their family. For some conditions very early diagnosis and treatment can make a difference for the child. -

Blueprint Genetics Comprehensive Growth Disorders / Skeletal
Comprehensive Growth Disorders / Skeletal Dysplasias and Disorders Panel Test code: MA4301 Is a 374 gene panel that includes assessment of non-coding variants. This panel covers the majority of the genes listed in the Nosology 2015 (PMID: 26394607) and all genes in our Malformation category that cause growth retardation, short stature or skeletal dysplasia and is therefore a powerful diagnostic tool. It is ideal for patients suspected to have a syndromic or an isolated growth disorder or a skeletal dysplasia. About Comprehensive Growth Disorders / Skeletal Dysplasias and Disorders This panel covers a broad spectrum of diseases associated with growth retardation, short stature or skeletal dysplasia. Many of these conditions have overlapping features which can make clinical diagnosis a challenge. Genetic diagnostics is therefore the most efficient way to subtype the diseases and enable individualized treatment and management decisions. Moreover, detection of causative mutations establishes the mode of inheritance in the family which is essential for informed genetic counseling.

Rapadilino syndrome is a genetic disease characterized by a characteristic clinical tableau. It is caused by mutations in RECQL4 gene. Immunodeficiency is not described as a classical feature of the disease. We present a 2-year-old girl with Rapadilino syndrome with important lymphadenopathies and pneumonia due to disseminated Mycobacterium lentiflavum infection. An immunological work-up showed several unexpected abnormalities. Repeated blood samples showed severe lymphopenia. Immunophenotyping showed low T, B, and NK cells. No Treg cells were seen. T cell responses to stimulations were insufficient.
