Article Synopsis
  • Advances in molecular diagnostics have shown that certain genetic variants linked to neurodegenerative diseases can also cause severe neurodevelopmental disorders when inherited in a biallelic manner.* -
  • The study focuses on TOR1A-associated arthrogryposis multiplex congenita 5 (AMC5), revealing a range of clinical symptoms across a cohort of 57 individuals, including severe flexion contractures, developmental delays, and various motor issues.* -
  • The research identified a phenotypic spectrum from mild symptoms to severe disabilities, with a notable survival rate of 71% and a median mortality age of 1.2 months, mainly due to complications like respiratory failure.*

EMILIN1 deficiency causes arterial tortuosity with osteopenia and connects impaired elastogenesis with defective collagen fibrillogenesis.

Am J Hum Genet

December 2022

Center for Medical Genetics, Ghent University Hospital, 9000 Ghent, Belgium; Department of Biomolecular Medicine, Ghent University, 9000 Ghent, Belgium. Electronic address:

EMILIN1 (elastin-microfibril-interface-located-protein-1) is a structural component of the elastic fiber network and localizes to the interface between the fibrillin microfibril scaffold and the elastin core. How EMILIN1 contributes to connective tissue integrity is not fully understood. Here, we report bi-allelic EMILIN1 loss-of-function variants causative for an entity combining cutis laxa, arterial tortuosity, aneurysm formation, and bone fragility, resembling autosomal-recessive cutis laxa type 1B, due to EFEMP2 (FBLN4) deficiency.

Background: Thyroid ultrasonography is the first and perhaps most fundamental step for the radiological distinction of benign and malignant nodules. In this study, 2 radiologists reviewed the sonoelastographic and Doppler images of thyroid nodules and evaluated for the intraobserver and interobserver reliability.

Purpose: We aimed to determine confusing nodule identifiers and sonographic features differently defined by observers.

Crisponi/cold-induced sweating syndrome (CS/CISS) is a rare autosomal recessive disorder characterized by episodic hyperthermia, arthrogryposis, impaired feeding ability, and respiratory distress. The classic CS/CISS is mainly associated with CRLF1 and, rarely, CLCF1. PERCHING syndrome, previously known as CS/CISS type-3 associated with biallelic pathogenic variants in KLHL7, is notable for its few overlapping manifestations.

How to Manage Low Estriol Levels in Pregnancies, One Center Experience.

Medeni Med J

March 2022

University of Health Sciences Turkey, Basaksehir Cam and Sakura City Hospital, Clinic of Obstetrics and Gynecology, Division of Perinatology, Istanbul, Turkey.

Objective: Low estriol (uE3) levels in the second-trimester screening for Down syndrome may be the result of fetal demise, congenital abnormalities, or some genetic hormonal disorders of the fetus. Although X-linked ichthyosis, a microdeletion syndrome with mild ichthyosis, which causes steroid sulfatase (STS) deficiency, is the most common genetic cause, second-trimester screening tests calculate the risk for a less common and severe disorder known as the Smith Lemli Opitz syndrome (SLOS). We aimed to investigate the outcomes of pregnancies with low uE3 levels in Down syndrome screening and emphasize the high prevalence of STS deficiency instead of SLOS in such cases.

Pediatric Urinary System Neoplasms: An Overview and Update.

Radiol Clin North Am

July 2017

Department of Radiology, Boston Children's Hospital, Harvard Medical School, 300 Longwood Avenue, Boston, MA 02115, USA.

Pediatric urinary system neoplasms are a diverse group of tumors that frequently overlap in their clinical and radiologic features. By contrast, the histopathologic classification and treatment of these entities have become increasingly refined, resulting in improved outcomes, with the overall survival of Wilms tumors now exceeding 90%. Significantly, many contemporary protocols rely on radiologic diagnosis in the absence of tissue confirmation.

Purpose: To compare effects of small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (F-LASIK) on corneal sensation and dry eye parameters.

Methods: In this prospective, randomized, contralateral-eye study, 28 patients with myopia or myopic astigmatism in both eyes were enrolled. One eye of each patient was treated by SMILE, and the fellow eye was treated by F-LASIK.

The aim of this study was to investigate the effects of caffeic acid phenethyl ester (CAPE) in the lungs by biochemical and histopathological analyses in an experimental isolated lung contusion model. Eighty-one male Sprague-Dawley rats were used. The animals were divided randomly into four groups: group 1 (n = 9) was defined as without contusion and without CAPE injection.
