The parents of a seven-year-old boy in need of a stem cell donor said they are living on a 'knife edge'.
Finley Hill, from Belbroughton in Warwickshire, suffers from a rare immune system disorder called hemophagocytic lymphohistiocytosis (HLH).
Disorder - System - Inflammation - Damage - Tissues
The disorder causes the immune system to overreact, leading to inflammation and damage to tissues such as the liver, spleen and brain.
His parents Jo and Paul are now urging people to sign up and donate in a desperate search for a match for their son.

This means many people with blood cancer and blood disorders die waiting for a matching donor.
Mrs Hill said: 'They haven’t given a time, but the medication won’t last forever. We’re all on a knife edge.'
HLH - Symptoms - Organs - Individuals - Fevers
HLH symptoms can vary greatly and it involves multiple organs. Generally, affected individuals develop fevers, a rash, and an abnormally large liver and spleen.
For Finley, his brain was the first to be affected. Some HLH patients develop neurological symptoms including seizures, mood changes, headaches, altered consciousness, and altered vision.
Mrs - Hill - 'When - School - Goodbye
Mrs Hill said: 'When we walk into school that saying goodbye is hard. He'll say, "I have a headache" and I don’t know, I can’t see. I don't know if it's a bit of anxiety or the inflammation is returning.
'We can’t be permanently MRI-ing...
