VEGF-A Gene Polymorphisms and Responses to Intravitreal Ranibizumab Treatment in Patients with Diabetic Macular Edema
The purpose of this study was to investigate the association between VEGF gene polymorphisms and the responses to treatment with intravitreal ranibizumab (IVR) in patients with diabetic macular edema (DME). This prospective study, conducted at the Kutahya Dumlupinar University Faculty of Medicine,…

Lyso-SM-509 Is a Highly Specific and Sensitive Biomarker for the Identification of Niemann-Pick Patients: a 30 Months Study
We present data from a 2 year global cohort of Niemann Pick patients using lyso-SM-509 biomarker determination, followed by sequencing of NPC1/2 genes. Determination of lyso-SM-509 is performed by LC/MRM-MS in plasma, serum, EDTA blood anddried blood spots (DBS). We identified in a world-wide study…

C26Cer Is a Highly Sensitive Screening Biomarker for Farber Disease Based on Dry Blood Test (DBS)
The new biomarker can be determined directly in the dried blood spot (DBS) extract with low sample consumption, easy sample preparation, high reproducibility and it presents the possibility of being used in high throughput screenings.

Clinical and Genetic Characteristics of Sporadic Adult-Onset Degenerative Ataxia
The objective of this study is to define the clinical phenotype and natural history of sporadic adult-onset degenerative ataxia and to identify putative disease-causing mutations. The primary measure of disease severity was the Scale for the Assessment and Rating of Ataxia (SARA). DNA samples were…

Glucosylsphingosine (lyso-Gb1) Plays a Central Role in the Diagnosis and Proper Assessment of Disease Severity in Gaucher Patients
We have developed and systematically validated a high-throughput workflow for the simple testing of GD patients: beta-glucocerebrosidase enzymatic activity, glycosylsphingosine (lyso-Gb1) quantification in DBS followed by GBA gene sequencing from the sample blood sample. We report data from over 940…

Biochemical and Genetic Data from the Largest Global Fabry Cohort Reported to Present
Fabry disease is an X-linked inherited lysosomal storage disease characterized by a deficient alpha-galactosidase caused by mutations in GLA gene. We present here the data collected over a period of over10 years regarding in vitro Fabry diagnosis.

Heart and Nervous System Pathology in Compound Heterozygous Friedreich Ataxia
In a small percentage of patients with Friedreich ataxia (FA), the pathogenic mutation is compound heterozygous, consisting of a guanine–adenine–adenine (GAA) trinucleotide repeat expansion in one allele, and a deletion, point mutation, or insertion in the other. In 2 cases of compound heterozygous…

Activation of PKC Triggers Rescue of NPC1 Patient Specific iPSC Derived Glial Cells from Gliosis
Niemann-Pick disease Type C1 (NPC1) is a rare progressive neurodegenerative disorder caused by mutations in the NPC1 gene. The pathological mechanisms, underlying NPC1 are not yet completely understood. Especially the contribution of glial cells and gliosis to the progression of NPC1, are…

BioTyrosin – Biomarker for Tyrosinemia Type 1 Disease
Hereditary Tyrosinemia type 1 (HT-1) is a rare genetic disorder in which the newborn child lacks the ability to break down the amino acid tyrosine. As a result of this deficiency, toxic substances build up in the blood and can cause liver failure, kidney dysfunction and neurological problems. The…
