Abstract: Poland’s syndrome (PS) is a rare musculoskeletal congenital anomaly with a wide spectrum of presentations. It is typically characterized by hypoplasia or aplasia of pectoral muscles, mammary hypoplasia and variably associated ipsilateral limb anomalies. Limb defects can vary in severity, ranging from syndactyly to phocomelia. Most cases are sporadic but familial cases with intrafamilial variability have been reported. Several theories have been proposed regarding the genesis of PS. Vascular disruption theory, “the subclavian artery supply disruption sequence” (SASDS) remains the most accepted pathogenic mechanism. Clinical presentations can vary in severity from syndactyly to phocomelia in the limbs and in the thorax, rib defects to severe chest wall anomalies with impaired lung function.

  • 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.

  • Craniosynostosis Precision Panel Overview Indications Clinical Utility
    Craniosynostosis Precision Panel Overview Craniosynostosis is defined as the premature fusion of one or more cranial sutures, often resulting in abnormal head shape. It is a developmental craniofacial anomaly resulting from a primary defect of ossification (primary craniosynostosis) or, more commonly, from a failure of brain growth (secondary craniosynostosis). As well, craniosynostosis can be simple when only one suture fuses prematurely or complex/compound when there is a premature fusion of multiple sutures. Complex craniosynostosis are usually associated with other body deformities. The main morbidity risk is the elevated intracranial pressure and subsequent brain damage. When left untreated, craniosynostosis can cause serious complications such as developmental delay, facial abnormality, sensory, respiratory and neurological dysfunction, eye anomalies and psychosocial disturbances. In approximately 85% of the cases, this disease is isolated and nonsyndromic. Syndromic craniosynostosis usually present with multiorgan complications. The Igenomix Craniosynostosis Precision Panel can be used to make a directed and accurate diagnosis ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes involved. Indications The Igenomix Craniosynostosis Precision Panel is indicated for those patients with a clinical diagnosis or suspicion with or without the following manifestations: ‐ Microcephaly ‐ Scaphocephaly (elongated head) ‐ Anterior plagiocephaly ‐ Brachycephaly ‐ Torticollis ‐ Frontal bossing Clinical Utility The clinical utility of this panel is: - The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient. - Early initiation of treatment in the form surgical procedures to relieve fused sutures, midface advancement, limited phase of orthodontic treatment and combined 1 orthodontics/orthognathic surgery treatment.

The clinical and radiological signs, specific for this congenital malformation, are described. A surgical intervention, consisting in soft tissue reconstruction and repositioning of the radius and ulna, was performed. The presented case is unique for our country for this canine breed and, furthermore, one of the first cases of therapeutic intervention via plastics of the skin cleft with additional stabilization of the carpal joint by placing a wire cerclage of the radius and the ulna.

ABSTRACT Authors present a very rare case of tetra-phocomelia evaluated by antenatal ultrasonography. It is a condition seen in 0.62 per 100,000 live births. This is a congenital chromosomal abnormality involving the musculoskeletal system. Primi gravida with spontaneous conception after a long period of infertility underwent early anomaly scan. Patient was not aware of the last menstrual period hence; NT scan was missed. Routine early anomaly scan done between 16- 18 weeks of pregnancy diagnosed a fetus with Tetra-Phocomelia. Due to the lack of associated symptoms or significant history, our case did not fit into any specific syndrome and appears to be the result of a sporadic, non- hereditary limb deficiency involving all four limb buds.

SUMMARY Neural tube defects (NTDs) may be associated with syndromes, disorders and maternal risk factors. This article provides a comprehensive review of the syndromes, disorders and maternal risk factors associated with NTDs, including DK phocomelia syndrome (von Voss-Cherstvoy syndrome), Siegel-Bartlet syndrome, fetal warfarin syndrome, craniotelencephalic dysplasia, Czeizel-Losonci syndrome, maternal cocaine abuse, Weissenbacher- Zweymüller syndrome, parietal foramina (cranium bifidum), Apert syndrome, craniomicromelic syndrome, XX- agonadism with multiple dysraphic lesions including omphalocele and NTDs, Fryns microphthalmia syndrome, Gershoni-Baruch syndrome, PHAVER syndrome, periconceptional vitamin B6 deficiency, and autosomal dominant Dandy-Walker malformation with occipital cephalocele. NTDs associated with these syndromes, disorders and maternal risk factors are a rare but important cause of NTDs. The recurrence risk and the preventive effect of mater- nal folic acid intake in NTDs associated with syndromes, disorders and maternal risk factors may be different
