High prevalence of weak<scp>D</scp>type 42 in a large‐scale<scp><i>RHD</i></scp>genotyping program in the province of<scp>Quebec (Canada)</scp>

Abstract

Our RHD genotyping program allowed for a better management of weak D. The province of Quebec presents a unique RHD genotype distribution. We confirmed that weak D type 42 is associated with a founder effect found in Caucasian French Canadians.
