Webdon). This implies that for a given Ig/TCR locus, very fre-quently two rearrangement attempts have taken place: one on each chromosome (allele). Given that the theoretical chance for a rearrangements to be in the correct reading frame and lacking a stop codon is ~25–30%, this implies that biallelic Ig/TCR gene rearrangements (D–Jand/orV ...
