Letter: Serum alpha-fetoprotein in cystic fibrosis.

Professor R. K. Chandra and others found raised serum levels of alpha-fetoprotein 
(AFP) in a heterozygote carrier of the gene for cystic fibrosis 
and in patients with the disease and some of the siblings. 
Our results do not show any significant difference in AFP levels 
in patients, siblings, parents, or control children. Probably the discrepancy in 
the findings will be explained by more detailed examination of the 
technique used.
