At Hacettepe, 3 children with the same SAMHD1 change showed very different symptoms
A study published in a journal and reviewed by independent scientists. Even so, a single study is not conclusive; it needs to be replicated.
The SAMHD1 gene causes one type of Aicardi-Goutières syndrome. At Hacettepe, three children carrying the same change in this gene were studied. One had muscle involvement, one had the classic findings, and one had a lupus-like picture. All received a JAK inhibitor drug and improved partially or lastingly. When the drug was paused, the symptoms returned.
What does it mean for patients and families?
This is a report describing only three children. In children with unexplained signs of inflammation, genetic testing may help with early diagnosis; treatment decisions are made with the doctor.
