EXTENDED CARRIER SCREENING Peace of Mind for Planned Pregnancies
Focusing on Personalised Medicine EXTENDED CARRIER SCREENING Peace of Mind for Planned Pregnancies Extended carrier screening is an important tool for prospective parents to help them determine their risk of having a child affected with a heritable disease. In many cases, parents aren’t aware they are carriers and have no family history due to the rarity of some diseases in the general population. What is covered by the screening? Genomics For Life offers a comprehensive Extended Carrier Screening test, providing prospective parents with the information they require when planning their pregnancy. Extended Carrier Screening has been shown to detect carriers who would not have been considered candidates for traditional risk- based screening. With a simple mouth swab collection, we are able to test for over 419 genes associated with inherited diseases, including Fragile X Syndrome, Cystic Fibrosis and Spinal Muscular Atrophy. The assay has been developed in conjunction with clinical molecular geneticists, and includes genes listed in the NIH Genetic Test Registry. For a list of genes and disorders covered, please see the reverse of this brochure. If your gene of interest is not covered on our Extended Carrier Screening panel, please contact our friendly team to assist you in finding a gene test panel that suits your needs. Why have Extended Carrier Screening? Extended Carrier Screening prior to pregnancy enables couples to learn about their reproductive risk and consider a complete range of reproductive options, including whether or not to become pregnant, whether to use advanced reproductive technologies, such as preimplantation genetic diagnosis, or to use donor gametes. -

Harlequin Ichthyosis
orphananesthesia Anaesthesia recommendations for patients suffering from Harlequin ichthyosis Disease name: Harlequin ichthyosis ICD 10: Q80.4 Synonyms: Harlequin baby, ichthyosis congenita, Ichthyosis fetalis, keratosis diffusa fetalis, Harlequin fetus, Ichthyosis congenita gravior Disease summary: Harlequin ichthyosis (HI) is an autosomal recessive congenital ichthyosis. HI is an extremely rare and most severe form of ichthyosis. The condition is caused by mutation of the ABCA12 gene resulting in impaired lipid transport in the outermost layer of the skin, the epidermis. During the neontatal period, harlequin ichthyosis manifests phenotypically as dramatic large polygonal plate-like scaling of the skin that cracks and can slough, revealing the underlying diffusely bright red skin. These thick skin plates can pull and distort facial features. The tightness of the skin can also pull on the eyes and mouth resulting in difficulties with closing these structures. The tightness also causes the eyes and the mouth to turn inside out resulting in ectropion and eclabium. Other features include hypoplasia of the fingers, malformation of the ears and nose, and alopecia. Affected neonates often do not survive and mortality is commonly attributed to respiratory failure and/or sepsis. Clinical data obtained from 45 HI patients revealed 25 survivors and 20 deaths with an overall survival rate of only 56%. The ages of survivors ranged from 10 months to 25 years and death usually occurred in the first 3 months. HI infants need to be cared for in a neonatal intensive care unit immediately after birth. Several harlequin neonates have survived. They tend to have severe erythroderma and fine scaling, even with optimal management. -

Epidermolytic Hyperkeratosis with Ichthyosis Hystrix Geromanta Baleviciené, MD, Vilnius, Lithuania Robert A
pediatric dermatology Series Editor: Camila K. Janniger, MD, Newark, New Jersey Epidermolytic Hyperkeratosis With Ichthyosis Hystrix Geromanta Baleviciené, MD, Vilnius, Lithuania Robert A. Schwartz, MD, MPH, Newark, New Jersey Epidermolytic hyperkeratosis (EH) is a congenital, autosomal-dominant genodermatosis characterized by blisters.1,2 Shortly after birth, the infant’s skin becomes red and may show bullae. The erythema regresses, but brown verrucous hyperkeratosis persists, particularly accentuated in the flexures. This condition is also known as bullous ichthyosiform erythroderma. The disorder of keratinization has varied clinical manifestations in the extent of cutaneous involve- ment, palmar and plantar hyperkeratosis, and evi- dence of erythroderma. We describe 5 patients, 4 with EH (one of whom had it in localized form and one of whom had an unusual type of ichthyosis hystrix described by Curth and Macklin3-7). Case Reports FIGURE 1. Seven-year-old girl with EH, demonstrating Patient 1—A 7-year-old girl with a cutaneous erup- erythema and verrucous hyperkeratosis (Patient 1). tion since birth characterized by flaccid bullae vary- ing in size. The palms and soles had intense diffuse keratosis from 1 year of age. Her nails, hair, teeth, and mental state were normal. The patient’s mother (Pa- tient 2) had a similar disorder. Skin biopsy specimens showed the changes of EH, with pronounced cellular vacuolation of the middle and upper portions of the malpighian stratum and large, clear, irregular spaces. Cellular boundaries were indistinct. A thickened granular layer was evident with large, irregularly shaped keratohyalin granules. Ultrastructural study showed tonofilament clumping of the malpighian layer and cytolysis. -

Fetal Harlequin Ichthyosis – a Case Report
IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) e-ISSN: 2279-0853, p-ISSN: 2279-0861.Volume 14, Issue 11 Ver. I (Nov. 2015), PP 81-86 www.iosrjournals.org Fetal Harlequin Ichthyosis – A Case Report Sunita Nayak1, Suren Prasad Dash2, Muktikanta Khatua3 1Tutor, Department of Anatomy, SCB Medical College, Cuttack, Odisha, India 2Consultant Radiologist, Sahara Diagnostics, Courtpeta Square, Berhampur, Odisha, India 3Assistant Surgeon, District Headquarter Hospital, Koraput, Odisha, India Abstract: Ichthyosis refers to a relatively uncommon group of skin disorders characterized by the presence of excessive amounts of dry surface scales. Autosomal recessive congenital ichthyosis (ARCI) encompasses several forms of nonsyndromic ichthyosis. Although most neonates with ARCI are collodion babies, the clinical presentation and severity of ARCI may vary significantly, ranging from harlequin ichthyosis, the most severe and often fatal form, to lamellar ichthyosis (LI) and (nonbullous) congenital ichthyosiform erythroderma (CIE). This is a case report of congenital (Harlequin) ichthyosis which is also called harlequin fetus, a lethal keratinising disorder. An externally thickened keratin layer of skin and diffuse plate like scales characterize it. Prenatal sonographic diagnosis has been described, with 2D findings of a persistently open mouth, echogenic amniotic fluid and fixed flexion deformity of the extremities. The 3D sonographic features have been described showing the morphological appearance typical of harlequin fetus, namely the open mouth with thick lips. The most definitive prenatal sonographic diagnosis of this condition is by 3D, which may not be done routinely without a suspicious 2D feature. In this case report, we suggest that the appearance of facial profile is the most easily seen and earliest 2D feature of this condition. -
