In the remote northern Brazilian state of Roraima, twin sisters Elis and Eloá Lima Carneiro have captured global attention not only for their close bond but for living with one of the rarest genetic conditions known to medicine. Born in May 2021 in Boa Vista after a premature delivery at 32 weeks, the identical (monozygotic) girls were later diagnosed with Hutchinson-Gilford Progeria Syndrome (HGPS), commonly known as progeria—a disorder that causes rapid, premature aging.

Progeria is extremely rare, affecting roughly one in 4 million to 20 million births worldwide, with only about 350–400 known cases globally. According to the Progeria Research Foundation in the United States, Elis and Eloá represent the first and only confirmed pair of twins with the condition. The syndrome stems from a spontaneous mutation in the LMNA gene, which produces an abnormal protein called progerin. This leads to accelerated cellular aging, typically beginning in the first year of life.

Their mother, Elismar Lima Carneiro, a seamstress and single parent raising a large family of around ten children, noticed early signs when the girls were about four months old. Their skin began to thin and wrinkle, hair started falling out, their mouths appeared small, and they lacked a defined chin. Growth lagged dramatically. By seven months, specialists raised the possibility of progeria; the formal diagnosis followed around their first birthday, later confirmed by genetic testing detecting a heterozygous LMNA mutation. The girls’ father left the family after the condition was suspected and did not register the children.

Today, at ages three and four (as of reports through 2025), Elis and Eloá remain very small—around 5–6 kilograms in weight and about 60 centimeters tall—with the characteristic appearance of progeria: bald heads, prominent eyes, thin limbs, and aged-looking skin. Yet their cognitive and emotional development proceeds normally. They are curious, communicative, playful, and closely attached to each other. Family members describe them as “the joy of the house.” Older siblings, including brother Pedro Guilherme Iago, who helps manage their care and social media, play key supporting roles while Elismar works.

There is no cure for progeria. Without treatment, average life expectancy is roughly 13–14.5 years, with most deaths resulting from cardiovascular complications such as heart attack or stroke. The twins, however, receive the drug lonafarnib (Zokinvy), the first FDA-approved therapy for the condition, supplied through the Progeria Research Foundation. The medication helps slow the production of progerin and has been associated with extended lifespan and delayed progression of symptoms. They also benefit from nutritional support, physiotherapy, speech therapy, and occupational therapy. Family members report that the girls continue to gain new skills, become more independent, and show improved vitality year by year.

The family’s openness has turned their story into a powerful platform for awareness. Their Instagram account has grown to more than one million followers, while related content on TikTok has reached millions of views. Posts share everyday moments, developmental milestones, and educational information about the syndrome, transforming personal vulnerability into collective support and visibility for a little-known disease.

Elismar has spoken candidly about the emotional weight of the diagnosis and the uncertainty of the future, yet she emphasizes living in the present and celebrating every small victory. “They are learning something new every day,” she has said. For the family, each birthday—especially the girls’ third and fourth—marks not just another year but tangible progress against the odds.

Elis and Eloá’s story highlights both the harsh realities of an ultrarare genetic disorder and the resilience of a family determined to give two little girls the fullest possible childhood. Their unique status as the world’s only known progeria twins continues to draw scientific interest while inspiring thousands who follow their journey of courage, love, and everyday triumphs.
