RHD*01W.155 (expected) - RHD*weak D type 155 (expected)
(ISBT table: not listed)
This entry is an RHD allele.
RHD(A237V), RHD*710C>T, RHD*710T, RHD*710T (weak D type 155), weak D type 155,
Molecular data
Nucleotides:
710C>T;
Amino acids: A237V;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
Extracellular position of one or more amino acid substitutions:
- none of the mutations are predicted to affect an extracellular amino acid
- change listed as predicted to be in the "eigth loop of the transmembrane protein", probably a typo for "8th transmembrane domain"
Splicing:
Unconventional prediction methods:

Reports
Summary: exceptional description(s), mainly in Asian individuals (including the Indian subcontinent), or compatible with such descent (last update: June 11, 2020)Detailed reports
- 1/62 D variant donors Chinese, Southern Han
- 1/223 donors with D negative phenotype initially, found to have D antigen expression (67 of the 223 samples of the cohort) or samples referred with discrepant or weak D typing, or discrepancies with previous typings, or anti-D in D positive individuals (156 of the 223 samples of the cohort) in the Indian population
