Rayan, a Pakistani toddler aged 8 months became the youngest bone marrow donor by donating his healthy bone marrow to his 2-year-old sister.
The successful operation took place in a hospital situated in Bengaluru, India.
The two-year-old Zeenia who originates from Sahiwal, Pakistan, was suffering from a disease called Hemophagocytic Lymphohistiocytosis (HLH).
It is a rare disease in which the brain starts to produce abnormal cells which tend to eat away healthy cells in the body.
As a result, the victim experiences high fever, liver and spleen enlargement and low blood count.
This life-threatening disease had only one solution: A healthy bone marrow transplant.
But the doctors needed a matching set of bone marrow in order to transplant.
They ran tests for her 8 months old brother and found out that he was Human Leukocyte Antigen (HLA) match for his sister.
Since the child was very young of age, the doctors could not extract the healthy bone marrow in a single session. So they had to proceed with the donation process over a few weeks.
They collected the bone marrow twice a week for few weeks until adequate quantities were in their hand for the cure.
Zeenia was then put through the transplant procedure.
Zeenia has now been cured and is ready to head back to Pakistan to live a healthy life.
Her brother Rayan, is also healthy and ready to go back to Pakistan.
