dence for a positive association between a health 
condition researched and a toxic exposure risk activ-
ity (as defined in section 1710(e)(4) of title 38, 
United States Code) based on the categories set 
forth under section 1173(c)(2) of title 38, United

retary of Veterans Affairs shall conduct a study on 
the biological descendants of veterans who served in 
Operation Ranch Hand to—

developmental delays among such descendants; 
and 
(B) identify— 
(i) genetic factors that prevented 
some of such descendants from developing 
such a birth defect or developmental delay; 
(ii) causes of related health outcomes; 
and 
(iii) preventative measures to mitigate 
risks associated with toxic exposures.
