Progeria, also known as Hutchinson-Gilford progeria syndrome (HGPS), is an extremely rare genetic disorder characterized by accelerated aging in children. According to available data, it is estimated that worldwide there are approximately 1 in 18 to 1 in 20 million live births affected by progeria.
Given the rarity of the condition, the number of children diagnosed with progeria is relatively small. As of my knowledge cutoff in September 2021, there were around 400 known cases of progeria reported worldwide. However, it’s important to note that this number may have changed since then due to new diagnoses or advancements in medical research. For the most up-to-date and accurate information, it is recommended to consult recent medical literature or contact relevant medical organizations that specialize in progeria.
