GENETICS OF CYSTINOSIS
C = normal gene / non-cystinosis gene
c = recessive gene /cystinosis gene
Cc = carrier / heterozygote / no cystinosis
CC = non carrier / no cystinosis
cc = cystinosis
If two people who are carriers for the cystinosis gene have a child there is a :
- 1 in 4 chance the child will have cystinosis (cc)
- 2 in 4 chance the child will not have cystinosis, but will be a carrier (Cc)
- 1 in 4 chance the child will not have cystinosis or be a carrier (CC)
