(ISBT table: not listed)
This entry is an RHD allele.
RHD(IVS3+5G>A), RHD*486+5A, RHD*486+5A (IVS3+5A), RHD*486+5G>A,
Molecular data
Nucleotides:
intronic 486G>A;
Amino acids: 0;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
Extracellular position of one or more amino acid substitutions:
- Silent or intronic mutations: none of the mutations are predicted to affect an extracellular amino acid.
Splicing:

Reports
Summary: rare descriptions, in the Swiss and French population (last update: Dec. 22, 2019)Detailed reports
- 2/289 289 samples with ambiguous D phenotype (333 consecutive samples with ambiguous D phenotype studied but 44 were hybrid alleles, excluded from the study) in the French (Western France) population
-
1/26243 donors with D negative phenotype in three studies with different inclusion criteria in the Swiss population (Zurich and Berne)
(study may overlap with
24679597 ) -
1/25370 donors with D negative phenotype, screened for RHD exons 3 or 7, plus 5 and 10 in the Swiss population
(study may overlap with
24656493 ) - 1 hemizygote among 278 samples selected for the development of nonspecific quantitative next-generation sequencing. (non-random samples, may have been reported in other studies)
