NBS (Newborn Screening)
Newborn Screening

Overview


Newborn screening (NBS) is a critical public health initiative aimed at identifying serious genetic and metabolic disorders in infants shortly after birth. Early detection enables timely medical intervention, significantly reducing morbidity, mortality, and long-term disability associated with many inherited conditions.

The integration of Next-Generation Sequencing (NGS) into newborn screening has enabled comprehensive genomic analysis to identify disease-causing variants across multiple genes simultaneously. NGS-based screening enhances diagnostic accuracy, facilitates confirmatory testing, and enables detection of a broader spectrum of inherited disorders from a single assay. NGS-driven newborn screening supports precision medicine from the earliest stage of life by providing rapid and reliable genetic insights that guide early diagnosis, clinical management, and long-term care.

The Genes2Me Newborn Screening (NBS) NGS Kit is a targeted sequencing solution designed for comprehensive detection of genetic variants associated with inherited metabolic disorders, congenital conditions, and other clinically actionable neonatal diseases.

Designed for high-throughput laboratories and public health programs, the assay enables scalable, cost-effective genomic screening while maintaining high sensitivity, accuracy, and reproducibility.

Relevant Clinical Use Cases:


  • Abnormal Screening Results: Neonates or infants showing abnormal findings in routine biochemical tests, MS/MS screening, or failing standard hearing assessments.
  • Family History of Genetic Disorders: Newborns who appear healthy but have a documented family history of genetic conditions.
  • Clinical Warning Signs: Infants presenting symptoms such as prolonged jaundice, feeding difficulties, vomiting, diarrhea, or unexplained anemia.
  • Comprehensive Genetic Insight: Parents seeking a complete genetic health profile of their newborn for proactive care and informed decision-making.

Key features and highlights


  • Globally Trusted Standards: Built on internationally recognized guidelines and best practices to deliver rapid, accurate, and high-quality results.
  • Flexible Sample Compatibility: Supports both dried blood spots and peripheral blood for seamless and convenient testing.
  • Comprehensive & Accurate Detection: In-depth sequencing of coding regions to identify SNVs, Indels, and CNVs in a single streamlined analysis, ensuring unmatched precision.
  • Broad Disease Coverage: Safely screens for over 300 conditions across 335 genes associated with metabolic and genetic disorders.
  • Lifetime Genomic Insight & Expert Support: Employs advanced NGS-WES technology for secure data archiving, enabling future reanalysis, complemented by end-to-end support, scientific consultation for clinicians and personalized genetic counseling for families.

Conditions Screened by G2M NBS Test

The conditions screened by the G2M NBS test are categorized into key clinical groups. Each category includes examples of specific disorders along with their typical management approaches.

Metabolic Disorders

Disease Group Disorder Signs & Symptoms Care Pathway
Metabolic Amino Acid Metabolic Disorders Poor feeding or vomiting, failure to thrive, developmental delay, locomotor retardation. Special diets, medications, and nutritional supplements.
Organic Acid Metabolic Disorders Vomiting, hypoglycemia, hyperammonemia, seizures, hypotonia, lethargy, coma. Low-protein diet, carnitine supplementation, and additional dietary support.
Fatty Acid β-Oxidation Disorders Hypoketotic hypoglycemia, liver dysfunction, cardiomyopathy in neonates. Avoid fasting, prompt illness management, carnitine if required.
Endocrine Disorders Low energy, feeding difficulties, seizures, jaundice, organ enlargement. Tailored diet, medications, enzyme therapy, intensive care when needed.
Carbohydrate Metabolic Disorders Extreme fatigue, vomiting, weak muscle tone, seizures. Diet modification, supplements, medications, complication management.
Metabolic Epilepsy Diseases Seizures, breathing difficulties, hypotonia, abnormal movements. Phenobarbital first-line therapy; alternatives include levetiracetam or phenytoin.
Other Inborn Errors of Metabolism Weight loss, seizures, developmental delay, unusual urine or sweat odor. Prevent toxic metabolite accumulation, long-term dietary and medical therapy.

Genetic Disorders

Disease Group Disorder Signs & Symptoms Care Pathway
Genetic Deafness Lack of response to sound, delayed speech and language development. Medical intervention, hearing aids, cochlear implants.
Hemophilia B Prolonged bleeding after procedures, excessive bruising. Factor replacement therapy; gene therapy under evaluation.
β-Thalassaemia Fatigue, pallor, jaundice, dark urine, enlarged abdomen. Blood transfusion, iron chelation, stem cell transplant, folic acid.
Noonan Syndrome Distinct facial features, heart defects, growth delay. Growth hormone therapy, speech/behavior therapy, medications, surgery.
Marfan Syndrome Aortic enlargement, heart valve defects, eye and skeletal issues. Cardiac medication, surgery, activity limitation, orthopedic support.
