| Abstract: | The present study of 977 cystic fibrosis (CF) patients showed a bimodal birth distribution with peaks in April to July and October to January. After adjustment to the monthly variation of the birth rate of all liveborn children there was no significant deviation from the expected distribution. The 387 phenylketonuria (PKU) patients showed no seasonal birth variation. |
