AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for people with an inherited blood disorder of haemoglobin: sickle cell disease, beta-thalassemia or alpha-thalassemia. It studies genes that change how these diseases behave.

Age
2 years or older at the time the study data are collected.
Sex
All sexes can join. There are no limits by gender or ethnicity.
Disease stage
A clinical diagnosis of an inherited hemoglobinopathy: sickle cell disease, β-thalassemia or α-thalassemia. All genotypes are considered.
Earlier treatment
People who were treated with stem cell transplantation or genetic therapy cannot join.

Main reasons for not taking part

  • Treated with stem cell transplantation or genetic therapy
  • Younger than 2 years at the time the study data are collected
  • Patient, or legal representative for a minor, unwilling or unable to give consent

Study of the Role of Genetic Modifiers in Hemoglobinopathies

This study will investigate the role of genetic modifiers in hemoglobinopathies through a large-scale, multi-ethnic genome-wide association study (GWAS).

Inclusion: Clinical diagnosis of an inherited hemoglobinopathy, including sickle cell disease (SCD), β-thalassemia, and α-thalassemia; all genotypes will be considered; Age ≥ 2 years old at the time of the collection of the phenotypic data; There will be no limits on study participants in terms of gender, ethnicity, morbidities.

Exclusion: Patients treated with stem cell transplantation or genetic therapy; Age < 2 years old at the time of the collection of the phenotypic data; Patient or legal representative for minors unwilling or unable to give consent.
