Figure 3.
DNA sequences of the GPIBA gene showing the 27-bp deletion in the macroglycopeptide region. (A) Cloned fragment I from the GPIBA gene in the propositus showing a glycine codon at position 233 and methionine at 239 in both normal and mutant alleles. (B) Cloned fragment II from the GPIBA gene in the propositus showing the normal allele (no deletion [the 4373-4400 27 bp are boxed]) and the mutant allele (site of 27-bp deletion junction shown by an arrow).
