Alexandra Peraut is a Catalan girl with progeria; she has inspired the book Una nena entre vint milions ('A girl in 20 million'), a children's book to explain progeria to youngsters. [93] [94] Adalia Rose Williams, born December 10, 2006, was an American girl with progeria, who was a notable YouTuber and vlogger who shared her everyday life on ...
Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. [1] [2] The term progeroid syndrome does not necessarily imply progeria (Hutchinson–Gilford progeria syndrome), which is a specific type of progeroid syndrome.
In Hutchinson–Gilford progeria syndrome, a 50-amino acid deletion in prelamin A (amino acids 607–656) removes the site for the second endoproteolytic cleavage. Consequently, no mature lamin A is formed, and a farnesylated mutant prelamin A (progerin) accumulates in cells. [ 9 ]

The YouTuber, who had Hutchinson-Gilford syndrome, died on Wednesday night, according to posts on her social media accounts."January 12, 2022 at 7 pm Adalia Rose Williams was set free from this ...
Lonafarnib, a farnesyltransferase inhibitor, is an oral medication that helps prevent the buildup of defective progerin or progerin-like protein. [3] The effectiveness of lonafarnib for the treatment of Hutchinson-Gilford progeria syndrome was demonstrated in 62 patients from two single-arm trials (Trial 1/NCT00425607 and Trial 2/NCT00916747) that were compared to matched, untreated patients ...
Rothmund-Thomson syndrome and xeroderma pigmentosum display symptoms dominated by vulnerability to cancer, whereas progeria and Werner syndrome show the most features of "accelerated aging". Hereditary nonpolyposis colorectal cancer (HNPCC) is very often caused by a defective MSH2 gene leading to defective mismatch repair , but displays no ...
Progerin (UniProt# P02545-6) is a truncated version of the lamin A protein involved in the pathology of Hutchinson–Gilford progeria syndrome.Progerin is most often generated by a sporadic single point nucleotide polymorphism c.1824 C>T (GGC -> GGT, p.Gly608Gly) in the gene that codes for matured Lamin A. [1] This mutation activates a cryptic splice site that induces a larger mutation in the ...
