Comparison of the prevalence of the RN and Cce^s» haplotypes leading to partial RH2 antigen expression, for all SCD patient samples tested from 2010 to 2017^a

RHCE allele	Parisian area	Guadeloupe	French Guiana	All regions
Number of RH:2 patients tested	701	176	61	963
RN haplotype†	83 (11.8%)	2 (1.1%)	1 (1.6%)	90 (9.3%)
CceS haplotypes‡	151 (21.5%)	33 (18.8%)	7 (11.5%)	195 (20.2%)

^aPercentages represent the number of partial RH antigens, in the absence of conventional RH2 antigens, deduced from the molecular analysis, relative to the number of RH:2 patients tested.

^†RHD*01-RHCE*02.10.01.

^‡RHD*03N.01-RHCE*01.20.03 and RHD*01N.06-RHCE*01.20.03.
