Ehlers-Danlos syndrome (EDS) is a group of genetic connective tissue disorders that affect the body's ability to produce collagen. It is estimated to affect about 1 in 5,000 people worldwide. EDS can cause a range of symptoms including joint hypermobility, skin hyperextensibility, and tissue fragility. The impact of EDS can vary from mild to severe, affecting a person's quality of life and daily functioning. Early diagnosis and management by healthcare professionals are important in improving outcomes for individuals with EDS.
The prevalence of Down Syndrome worldwide is estimated to be around 1 in 1,000 live births. This prevalence can vary depending on factors such as maternal age. With advances in medical care and increased awareness, individuals with Down Syndrome are living longer, contributing members of society.
Marshall syndrome is a rare genetic disorder, with a prevalence that is not well documented in the general population. It is estimated to occur in fewer than 1 in 100,000 individuals. This means that less than 0.001% of the population is affected by Marshall syndrome.
Moebius syndrome is considered rare, with an estimated prevalence of 1 in 50,000 to 1 in 500,000 live births. This means that only a very small percentage of the general population is affected by this condition.
Zellweger syndrome is a rare genetic disorder with an estimated prevalence of 1 in 50,000 to 1 in 100,000 births. This translates to less than 0.001% of the population being affected by Zellweger syndrome.
1993 a woman (i'm not sure on her name) preformed a study on savants (there is a documentary following her travels with savants) and was able to contact about 50 (i do not know wheather or not they were of the autistic variety)
In 2015, the Australia Health Department stated that it does not collect data on the prevalence of autism.Autism appears to be on the rise. In 2015, autism made up 31% of the National Disability Insurance Scheme (NDIS) participants. Asperger's Syndrome is part of the autism spectrum. (This does not mean that 31% of the entire Australian population have Asperger's Syndrome or other forms of Autism.)
The continued improvements in treatments for Acquired Immune Deficiency Syndrome will only decrease its prevalence. An increase in cases of AIDS is exactly what scientists across the globe are working to prevent.
Recent estimates of prevalence suggest that TS occurs in one in 1,000 to one in 100 male children
Monosomy X mosaicism is a rare genetic condition where some cells in the body have only one X chromosome instead of the usual two. In individuals with Turner syndrome, this condition can occur and may have clinical significance. The prevalence of monosomy X mosaicism in Turner syndrome is not well established, but it can impact the severity and symptoms of the syndrome. It may lead to a more variable presentation of Turner syndrome, with some individuals experiencing more severe symptoms than others.

Noonan syndrome is estimated to occur in approximately 1 in 1,000 to 2,500 live births. This means that the prevalence may affect around 50,000 to 100,000 individuals in the United States alone, although exact figures can vary. The condition can be underdiagnosed due to its varying symptoms and presentations. Overall, the global prevalence remains difficult to determine precisely.
It is estimated that approximately 0.3% of the world's population has Tourette syndrome. This neurological disorder is characterized by repetitive, involuntary movements and vocalizations known as tics. Prevalence can vary by region and demographic factors.
