“Due to a genetic defect, those with the most widely publicized form of the condition, Hutchinson-Gilford progeria syndrome, age roughly ten years physiologically for each year of life.”

So do these individuals go through puberty at the calandar age of 1 1/2?

According to this article, puberty depends on the type of progeria:

@David Gems

Werner syndrome is the most common form of progeria. The first signs of this disorder appear only after puberty, with the full symptoms becoming manifest in individuals 20 to 30 years old. A much rarer progeria, Hutchinson-Gilford syndrome, develops earlier: victims die, apparently of old age, typically at around age 12.

I infer that Hutchinson-Gilford patients never reach puberty.
