Symptoms of GA1

Symptoms of GA1 usually dont appear until a few months after birth, although some babies are born with a larger-than-average head (macrocephaly).

Children with GA1 may develop some floppiness or weakness in their muscles ( hypotonia ) during their first year and theres a risk of developing bleeding around their brain ( subdural haematoma ). In rarer cases, bleeding can develop around the back of the eyes (retinal haemorrhage).
