Panel sequencing is being replaced In recent years, the use of genetic testing has become increasingly important in the diagnosis of rare diseases. With more than 7,000 rare diseases affecting over 400 million people worldwide, identifying the underlying genetic cause of these conditions can be a challenging task for clinicians. Panel sequencing has shown great…

The closure he needs: Genetically confirmed X-linked Agammaglobulinemia after 24-year wait We first saw Saravanan in our immunology clinic in 2021. Saravanan is a 40-year-old Indian man who was referred to us to establish a proper diagnosis for his underlying illness. He was initially managed by different doctors and later ended up without appropriate continuation…

Although in practice guidelines from the American College of Cardiology (ACC), American Heart Association (AHA), and Heart Rhythm Society recommend genetic testing for long QT syndrome, which causes ventricular arrhythmias, only 2.5% of patients receive it. Genetic Testing for Inherited Cardiovascular Disease Inherited Cardiovascular Disease is a group of genetic disorders that affect the heart and blood…

Many rare genetic diseases show similar symptoms. However, despite similar symptoms, the genetic cause may be different. Let us take a look into progressive muscular dystrophies for example. Progressive muscular dystrophy (PMD) is a genetic disease that leads to progressive weakness in the muscles. There are over 30 different types of dystrophy per genetic mutation,…

Introduction On the website of a company providing genetic testing for rare diseases, you can easily see “increases diagnostic yield by up to 20% compared to routine WES”1, “Approximately 30% diagnostic yield”2, “Detection rates range from about 28.8% to as high as 57.5% for this patient population”3.If you search for WES diagnosis yield on PubMed,…

There are several ways to perform genetic testing. The specific method used can depend on the type of genetic condition being tested for, the specific genes or genetic mutations being targeted, and the available resources. It’s important to note that genetic testing and diagnosis can be complex and may require multiple types of testing to…

Fabry disease actually has available treatments, so early diagnosis can have significant benefits for patients. In the past, when 1,200 patients previously diagnosed with HCM were retested, 20 of them were found to have Fabry disease. It is hard to distinguish between the two diseases based on the symptoms alone since both diseases are characterized…

2024 Update: Whole Genome Sequencing Costs The field of genetic testing, particularly Whole Genome Sequencing (WGS), is experiencing transformative growth, with the global Next-Generation Sequencing (NGS) market expected to expand significantly through 2030. The most impactful driver behind this expansion is the rapid decrease in sequencing costs, which has made genetic testing more accessible and…

We recently had the exhilarating opportunity to welcome Dr. Ngu to 3billion, a day that turned out to be both enlightening and inspiring for everyone involved. Dr. Lock Hock Ngu, MBBS (Malaysia), MRCP (UK), is a Head of Genetics at Hospital Kuala Lumpur. The institution serves as Malaysia’s national referral center for inherited metabolic diseases and…

The Advent of Whole Genome Sequencing in Rare Disease Diagnostics Whole Genome Sequencing (WGS) has revolutionized the approach to diagnosing rare diseases. Unlike traditional methods that target specific genes, WGS analyzes the entire genome, offering a comprehensive view of an individual’s genetic makeup. This approach has significantly increased diagnostic yield, especially for complex or undiagnosed…
