RPI Deficiency This is considered to be the rarest disease in the world. Ribose-5-Phosphate Isomerase (RPI), is a crucial enzyme in a metabolic process in the human body. This condition can cause muscle stiffness, seizures, and reduction of white matter in the brain.
According to the National Institutes of Health (NIH), there are approximately 7,000 rare diseases affecting between 25 and 30 million Americans.
The term low prevalence is later defined as generally meaning fewer than 1 in 2,000 people. Diseases that are statistically rare, but not also life-threatening, chronically debilitating, or inadequately treated, are excluded from their definition.
Cystic fibrosis (CF) is the most common, fatal genetic disease in the United States. About 30,000 people in the United States have the disease.
Currently, there are an estimated 7,000 known rare diseases. While rare diseases may be uncommon individually, together, these conditions affect more than 300 million people worldwide.
Approximately 80% of rare diseases are estimated to have a genetic origin. These rare diseases may suffer from missing heritability [15, 16]. One question worth asking is, how can we explain the missing heritability that might be the cause of the challenges we are facing in rare disease diagnostics?
There are more than 6000 distinct rare diseases in the EU. So, whilst one rare disease may affect only a handful of patients, another may touch as many as 245 000. Around 80% of rare diseases are of genetic origin and, of those, 70% already start in childhood.
1. The Black Death: Bubonic Plague. The Black Death ravaged most of Europe and the Mediterranean from 1346 until 1353. Over 50 million people died, more than 60% of Europe's entire population at the time.
Ischemic heart disease, or coronary artery disease
The deadliest disease in the world is coronary artery disease (CAD). Also known as ischemic heart disease, CAD occurs when the blood vessels that supply blood to the heart become narrowed. Untreated CAD can lead to chest pain, heart failure, and arrhythmias.
Scarlet fever, tuberculosis, mumps, measles: You may think these are deadly diseases of the past, wiped out with vaccines and antibiotics. The truth is that these diseases are still infecting people worldwide, and some have made resurgences in the U.S. Stay healthy and safe with the precautions outlined here.
Of the more than 6,800 rare diseases that have been identified, 72% are genetic. Seventy percent of rare genetic disorders start in childhood. A genetic disorder is caused by a change in a gene or group of genes which are present from birth.
Cause 1: Ischaemic heart disease
Ischaemic heart disease was the leading single cause of deaths in Australia, responsible for 17,331 deaths in 2021, about one in 10 of total deaths that year. Males were more prone to the disease, accounting for 10,371 (59.8%) of the deaths compared to 6,960 (40.2%) for females.
Foot-and-mouth disease (FMD), African swine fever (ASF) and Lumpy skin disease (LSD) are animal diseases and are not present in Australia. They do not pose human health concerns. Avian influenza (bird flu, AI) is a global disease of birds and some strains may affect humans.
The most expensive disease groups for admitted patients in public hospitals were Cardiovascular diseases, Injury and Gastrointestinal disorders. In private hospitals, these were Musculoskeletal disorders, Cardiovascular diseases, and Cancer and other neoplasms.
Prostate cancer, testicular cancer and other diseases of the male reproductive system occur in males. Diseases of X-linked recessive inheritance, such as colour blindness, occur more frequently in males, and haemophilia A and B occur almost exclusively in males.
Angelman syndrome
A rare syndrome causing physical and intellectual disability. It can't be cured, but some therapies can improve the quality of life of those affected....
