Down syndrome starts with a capital letter because it is named after John Langdon Down, the doctor who described the disorder in 1866.
According to Columbia Encyclopedia, the symptoms of Down syndrome were "first described in 1866 by an English physician, J. Langdon Down."

Sir john Langdon Down is credited with discovering Down's Syndrome. He first described it as a separate condition, but Jerome Lejeune discovered its chromosomal cause.
Down syndrome is the correct term. People who are using "Downs" are speaking incorrectly. Down syndrome used to be called Down's syndrome, but since John Langdon Down did not have nor "invent" this chromosomal abnormality, the correct name is Down syndrome. Countries such as the UK, still use the term Down's syndrome, but shortening it to Down's is not using people first language, therefore, it is incorrect.
John Langdon Down died in 1896.
