Furthermore, the estimates of regularity and penetrance for the condition allele suggest that the disease versions for familial interstitial pneumonia and idiopathic pulmonary fibrosis are equivalent. The chances ratio for disease among subjects who were heterozygous and those who have been homozygous for the rarer allele of the SNP were 6.8 and 20.8 , respectively, for familial interstitial pneumonia, and 9.0 and 21.8 , respectively, for idiopathic pulmonary fibrosis .Often, the reason for preterm delivery is unknown and not inside a mother’s control. Sometimes it’s due to the mother’s health conditions during being pregnant, such as for example gestational diabetes, hypertension, kidney or heart problems, an infection , or bleeding due to abnormal positioning of the placenta.

Also, early deliveries can be because of a structural abnormality or overstretching of the uterus from carrying more than one fetus .
