Outcome Measures

Primary Outcomes (1)

  • Genetic modifiers in haemoglobinopathies through GWAS

    Number of genetic variants (SNPs) associated with disease-specific phenotypes

    5 years

Study Arms (1)

Cohort

Individuals with hemoglobinopathies

Genetic: GWAS

Interventions

GWASGENETIC

The study will perform a GWAS experiments for all recruited subjects. The blood sample will be collected during routine clinical visits, only if DNA is not already available in existing biobanks. All individuals will provide consent for participation in the study.

Study Population

Individuals diagnosed with an inherited hemoglobinopathy and are under regular follow-up in the participating centers

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
