RHD*01W.41.0.1 - RHD*weak D type 41.0.1
(ISBT table: Weak D and Del v5.0)
This entry is an hybrid RHD allele.
RHD(L390L,E398V), RHD*1170C,1193T, RHD*1170C,1193T (weak D type 41.0.1), RHD*1170T>C,1193A>T, RHD*D-CE(9)-D, weak D type 41.0.1,
Molecular data
Nucleotides:
1170T>C; 1193A>T;
Hybrid allele encompassing at least one RHCE exon:
RHD-RHCE(9)-RHD
Comments on the molecular basis:
- "RHD*D-CE(9-D allele was deduced for loss of one copy signal for the RHD exon 9 by the MLPA and absence of variation by sequencing of exon 9 of the RHD gene, which still needs further confirmation."

Reports
Summary: rare descriptions, in Chinese, German, Danish (last update: April 2, 2020)Detailed reports
- 2 related samples investigation of HDN Caucasian Danish
- 1 sample reported by a USA lab from Wisconsin
- 1/200 (heterozygous with RHef00442) D positive donors tested by MPLA Chinese, Southern Han
- 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)
