FBF1 and rheumatoid arthritis: Thus, the goals of this research were to 1) assess whether active or sedentary lifestyles had any impact on the inhibition of recessive FBF1 risk to HYDS1 transmitted to next-generation progeny, 2) examine the inherited risk of FBF1 to HYDS1 being transmitted to progeny, whether from a normal father who exercised or a normal father who did not exercise, and 3) examine the risk of FBF1 to HYDS1 being inherited to offspring, whether from a father who exercised and had rheumatoid arthritis or a father without exercise who had rheumatoid arthritis.
