PCR product of a region of protein 4.2 cDNA encompassing exon 11.
PCR of a region of protein 4.2 cNDA encompassing exon 11 (nucleotides 1111-1797; numbered according to Sung et al2) produced a single band of 686 nucleotides from the control and a single band of 645 nucleotides from the proband. Unexpectedly, PCR of this region from the mother showed only a single band of 686 nucleotides.
