Human IGHV1-69 gene
Based on the
IMGT Alignment of alleles: Human IGHV1-69
 we can deduce from Figure 4 in , that there are two well known
IMGT IGHV1-69 alleles per individual.
Unfortunately, the authors did not check if the additional sequences in individuals 198 and 34 were
due to PCR artefacts or if they represented additional copies (and new alleles) of an eventual duplicated
IGHV1-69 gene. This would have been useful information regarding a potential duplication
(Marie-Paule Lefranc, 16/08/2006 in answer to a question of Felix Breden on the number of copies of the human IGHV1-69 gene).
