A vast majority, around 95% of the 7,000+ known rare diseases, currently lack an approved, specific treatment, with only about 5% having available therapies, leaving millions of patients with significant unmet medical needs, according to sources like the NIH, NORD, and The Lancet. This highlights a major challenge, as many are genetic and appear in childhood, with some causing severe lifelong disabilities.
For 95 % of these illnesses, there is no approved specific treatment. There are over 6,000 rare diseases, more than 80 % of them genetic in origin. Two out of three appear before the age of two; one in three patients suffers from motor, sensory or intellectual impairment, and one in five from chronic pain.
There are up to 10,000 rare diseases, however, only 5 percent of rare diseases have FDA-approved treatments.
Symptoms of Niemann-Pick disease relate to worsening function of the nerves, brain and other organs over time. Niemann-Pick disease can happen at different ages but mainly affects children. The condition has no known cure and is sometimes fatal.
Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured.
As anticipated, 2025 was a breakthrough year for gene therapy, and I expect 2026 to bring more exciting developments in the field. KJ Muldoon, a baby born with a rare genetic disease, became the first person to receive a customized CRISPR treatment.
Medical professionals call high blood pressure, also known as hypertension, the silent killer because it can go undetected for a long period of time and leads to death. Most people who have high blood pressure do not have any symptoms; testing is the only way to determine if someone has it.
Includes Creutzfeldt–Jakob disease and all its variants, fatal insomnia, kuru, Gerstmann–Sträussler–Scheinker syndrome, Variably protease-sensitive prionopathy and others. No cases of survival, invariably fatal.
Common: affecting between 1 in 10 people to 1 in 100 people (1% to 10%) Uncommon: affecting between 1 in 100 to 1 in 1,000 people (1% and 0.1%) Rare: affecting between 1 in 1,000 to 1 in 10,000 people (0.1% to 0.01%) Very rare: affecting less than 1 in 10,000 people (< 0.01%)
Leading Causes of Death
Genetic Disorders
A disease is conventionally defined “rare” when the number of affected subjects is <1:2,000 (i.e., <0.05%) in the European Union and <1:200,000 (i.e., <0.0005%) in the US, thus making the list of these conditions quite large, encompassing up to 8,000 pathologies, for some of which molecular or biochemical underlying ...
Abstract. The six killer diseases, malaria, tuberculosis, measles, acute lower respiratory infections, diphtheria, and whooping cough, represent the most significant contributors to the overall global burden of disease.
Heart disease, hypertension, and diabetes are major health threats that often progress silently without noticeable symptoms. specific silent killer diseases show no early symptoms.
Record numbers of men and women globally are now estimated to have reduced kidney function, a new study shows. Figures rose from 378 million people with the disease in 1990 to 788 million in 2023 as the world population grew and aged, making it for the first time a top 10 cause of death worldwide.
Smoking, physical inactivity and low SES account for almost two thirds of all avoidable deaths. (Meta-analysis data of prospective cohort studies, from Stringhini et al., Lancet 2017). A puzzling finding is the small contribution of obesity as a cause of avoidable premature death.
Based on an examination of our DNA, any two human beings are 99.9 percent identical. The genetic differences between different groups of human beings are similarly minute. Still, we only have to look around to see an astonishing variety of individual differences in sizes, shapes, and facial features.
Because human beings weren't able to manipulate the genetic code when the Bible was written, it doesn't directly address genetic engineering. It does, however, give general principles regarding medical technology that apply to genetic technologies.
The short answer is no. At least, not in the way pop culture often suggests. While modern fertility treatments offer powerful genetic insights, they don't let you pick traits like eye color, intelligence or personality.
