Filter by:Newborn screening (NBS) is a global initiative of systematic testing at birth to identify babies with pre-defined severe but treatable conditions. With a simple blood test, rare genetic conditions can be easily detected, and the early start of transformative treatment will help avoid severe disabilities and increase the quality of life. Baby Detect Project is an innovative NBS program using a panel of target sequencing that aims to identify 126 treatable severe early onset genetic diseases at birth caused by 361 genes. The list of diseases has been established in close collaboration with the Paediatricians of the University Hospital in Liege. The investigators use dedicated dried blood spots collected between the first day and 28 days of life of babies, after a consent sign by parents.
ScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 175,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.
Familial Hypercholesterolemia (FH) is a monogenic autosomal dominant disease also known as Autosomal Dominant Hypercholesterolemia - ADH) that leads to dramatically increased levels of Low Density Lipoprotein (LDL) and total cholesterol associated to tendon xanthomas, xanthelasma, corneal arcus, premature atherosclerosis and to an increased risk of coronary artery disease (CAD) and myocardial infarction. FH is mainly caused by mutations in genes encoding for proteins affecting hepatic LDL cholesterol uptake including the LDL receptor (LDLR) gene or the gene encoding the only apolipoprotein of LDL, the apolipoprotein B (APOB), or the gene encoding a protease regulating LDLR levels on the cell membrane Lysosomal Acid Lipase A (LIPA) gene encode for Lysosomal acid lipase (LAL) enzyme responsible for hydrolyzing cholesterol esters and triglycerides that are delivered to lysosomes. Mutations in LIPA that completely inactivate LAL are the molecular cause of Wolman disease, a rapidly lethal disease of infancy while mutations in LIPA that result in residual enzymatic activity of LAL are responsible of a disorder characterized by a less severe phenotype known as cholesterol ester storage disease (CESD). Patients with CESD usually show a phenotype characterized by hepatic disease and mixed hyperlipidemia with elevated levels of LDL-C and triglycerides (TG) and decreased HDL-C levels. A broader phenotypic presentation for loss of function mutations in LIPA suggests that LIPA mutations may be considered in patients with apparently monogenic FH in whom mutations in the known candidate genes are not detectable. The project is aimed to evaluate the prevalence and the mutation rate of LIPA gene in subjects with a clinical diagnosis of FH and already genetically characterized in whom pathogenic mutations in the known candidate genes have not been identified. The analysis will be performed in about 250 FH pediatric subjects and putative causal mutations will be also tested for co-segregation in available families in affected and unaffected members.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
The very low carbohydrates diet (VLCKD) induces liver steatosis amelioration. Lysosomal acid lipase (LAL) deficiency plays a role in fats accumulation in liver. To date, no studies have assessed LAL activity in morbid obesity. The aim of our study is to evaluate VLCKD impact on metabolic/vascular parameters and LAL activity in obese patients. A VLCKD is administered for 25 days to 52 morbid obese patients (BMI 44.7±8.3 kg/m², age 49±12.5 years); at baseline and after diet we evaluated: BMI, glyco-lipidic pattern, abdominal ultrasonography (liver steatosis and visceral fat area) and flow-mediated dilation (FMD). In a subgroup of 20 patients we also tested lysosomal acid lipase (LAL)-activity. A group of healthy normal weight subjects (age 43±13, BMI 22.8±2.6 kg/m²) was also included in the study.
The primary outcome of this study is the development of a clinical profile of pediatric patients with LAL-D, which will enable the Sponsor to provide more focused guidance to the medical community as to which pediatric patients should be tested for LAL-D.
This is an open-label, multicenter expanded access protocol to allow patients with a confirmed diagnosis of Lysosomal Acid Lipase (LAL) Deficiency in the United States (US), access to sebelipase alfa (recombinant lysosomal acid lipase [rhLAL]) until commercial product is available. Patients enrolled in the expanded access protocol will receive 1 mg/kg intravenous infusions of sebelipase alfa every other week.
The objective of this study is to determine the frequency of Lysosomal Acid Lipase Deficiency (LAL D) by lysosomal acid lipase (LAL) enzyme activity assay in patients who are considered to be at risk.
This was an open-label, repeat-dose, study of sebelipase alfa in infants with rapidly progressive lysosomal acid lipase deficiency (LAL-D). Eligible participants received once-weekly infusions of sebelipase alfa for up to 3 years.
This study evaluated the safety and efficacy of sebelipase alfa in a broad population of participants with lysosomal acid lipase deficiency (LAL-D).
