Newborn screening is a routine set of tests done in the first days of life to spot rare but treatable conditions early. A few drops of blood from your baby’s heel, plus hearing and heart checks, are usually all it takes. Finding a condition before symptoms appear lets doctors start treatment that can prevent serious…

NGS (next-generation sequencing) is a fast method that reads many genes at once to look for changes linked to disease. Medicare covers certain NGS tests, most clearly for advanced cancer and some inherited (germline) cancer risk situations that meet set rules. Coverage depends on medical necessity, an ordering physician, and specific diagnostic criteria — not…

Most baby health concerns like colic, mild rashes, and spitting up are normal and resolve on their own. Persistent or severe symptoms, such as significant feeding difficulties or missed developmental milestones, can be red flags. Some common issues can occasionally be the first sign of an underlying rare genetic condition. Genetic testing can provide definitive…

“My child has distinctive facial features, isn’t growing as tall as expected, and seems to be developing a bit more slowly than other children. Why would so many different symptoms appear across the whole body instead of just one organ?” Many rare genetic disorders arise from a defect in a single protein that affects only…

Bioinformatics is a field that uses computer science to understand complex biological data, especially DNA sequences. It is essential for interpreting the massive amount of data generated by modern genetic tests like whole exome sequencing. In rare disease diagnostics, bioinformatics helps pinpoint the specific genetic variant responsible for a patient’s symptoms from millions of possibilities.…

📍Key Takeaways Mitochondrial diseases are a group of genetic disorders that primarily affect the function of mitochondria, the energy-producing structures within cells. These disorders can arise from variants in either mitochondrial DNA or nuclear DNA. Variants in nuclear genes associated with mitochondrial function are often included in the targeted gene panels or exome sequencing tests…

“My child is a bit slow in development, but why are their height and head circumference growing so rapidly?”  Many parents naturally assume that if a child grows quickly, it simply means they have “excellent physical development” or have inherited a large build. However, if your child is exceptionally tall, has a large head, and…

Key Takeaways Sample-Level ‘Access Group’ In clinical genomic analysis, external expert consultations and multi-institutional collaborative research are becoming increasingly vital. However, in real-world operations, strict data security policies often make it incredibly difficult to share only the necessary samples safely. “I just want to share this specific sample to get an expert opinion, but I…
