Assessing ethnic neutropenia and Duffy null phenotype in newborns

Official title: The Prevalence of Ethnic Neutropenia in Neonates

Run by Kaplan Medical Center · NCT06908616 · Data updated 2026-11-12

This study is trying to see how common a specific genetic trait related to low white blood cell counts is in newborns at Kaplan Medical Center and how it connects to their ethnicity and health over time.

What this trial studies

This observational study aims to evaluate the prevalence of the Duffy null phenotype, which is associated with ethnic neutropenia, in neonates born at Kaplan Medical Center. Blood samples will be collected non-invasively from umbilical cords to assess Duffy antigen expression. The study will also gather data on ethnicity, perinatal factors, and routine blood counts at 9-12 months to correlate these with absolute neutrophil counts. The findings may provide insights into the genetic basis of neutropenia in certain ethnic groups and help clarify diagnostic approaches for affected infants.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic clarity and reduce unnecessary medical interventions for healthy infants with benign ethnic neutropenia.

How similar studies have gone: While studies on ethnic neutropenia exist, this specific approach to assessing the Duffy null phenotype in neonates is relatively novel.
