Scientists hunt for hidden genes behind rare childhood disease
NCT ID NCT02866162
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study looked for new genes that cause a rare condition called syndromic congenital neutropenia, where children are born with low infection-fighting white blood cells and other developmental issues. Researchers used advanced gene sequencing on 25 participants to find the genetic roots. The goal was to better understand the disease, not to test a treatment.
