  1. Nucleotides that alter between sequences are underlined. The identical sequences 2.3/2.14 and 1.10 are from two different patients (Patients 2 and 1, respectively). Note that the tyrosine (Y) at the second 5′ position of Jα 9.11, in the upper group of sequences, is substituted with a serine (S), with similar properties, in sequences 2.8 and 2.37.
