My mother has copd and has had for a long time . i'm pregnant and my dr told me i'm a carrier if cystic fibrosis. are these two in common or different?

Different: COPD is an acquired disease affecting the lower airways,usually related to tobacco smoke exposure,while cystic fibrosis is a genetic disease affecting several systems to a different degree,mainly the lungs.Only 25% of your offsprings would have it if your husband is a carrier too, Pre-Implantation Genetic Diagnosis (PIGD) can help in such cases by selecting the non affected embryos for implanting
