(ISBT table: weak D and Del v5.0)
This entry is an RHD allele.
RHD(IVS2-2A>G), RHD*336-2A>G, RHD*336-2G, RHD*336-2G (IVS2-2G, DEL33),
Molecular data
Nucleotides:
intronic 336A>G;
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.

Reports
Summary: rare descriptions, in the Danish and German populations (last update: Dec. 22, 2019)Detailed reports
- 1/2466 among donors with D negative phenotype, tested for RHD exons Danish (Copenhagen area)
- 2 samples in addition to the donor population study Danish (Copenhagen area)
- 1/136000 among about 136.000 donors with D negative phenotype, systematically tested for the presence of the RHD gene; the RHD gene was detected in 300 donors in the German population (some samples may overlap with other studies)
- 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)
