no
Comments on the molecular basis:
- see also "Additional comments" section on the RhesusBase http://www.rhesusbase.info/RHDRHD(IVS1-29GtoC).htm
- "Intron polymorphism"
- Table 6; 149-29G>C is an intronic polymorphism present in all samples with R1, R0 and RZ haplotypes
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.
