Dr. Uden continued, “Data from this analysis provide the first clear evidence of the extent to which ancestries beyond the Caucasian population can carry a higher risk for FNAIT, underscoring the importance of screening all pregnant women for FNAIT risk as part of standard prenatal care. This would ensure that all women at higher risk for FNAIT could then be offered prophylactic treatment with RLYB212, if approved.”\n\nThe ASHG abstract #7041T, which can be found here, details the high-level findings of the epidemiological analysis. In this analysis, women at higher risk for alloimmunization and FNAIT were defined as those having an HPA-1a negative and HLA-DRB3*01:01 positive genotype. Allele frequencies were obtained from gnomAD v4 for HPA-1a and the U.S. National Marrow Donor Registry (NMDR) for HLA-DRB3*01:01.\n\nProportions of women at risk of alloimmunizing were highest in Caucasian populations, with the highest proportions in the Ashkenazi Jewish population (2.36% and 0.65% of women at risk and at higher risk, respectively), followed by non-Finnish Europeans (2.34% and 0.64%), Middle Eastern (2.25% and 0.62%), Amish (2.25% and 0.62%), White Hispanic (2.25% and 0.59%) and Finnish (2.03% and 0.56%). Additionally, women in some non-Caucasian population groups were also found to be at risk including the Caribbean...
