Fig. 7.
PCR amplification with radio-labeled primers from MN1 locus (identified in the 3′ UTR region of the PAR-7 gene) from patient EE (middle lane), her mother (left lane) and her father (right lane). The mother showed two alleles (heterozygous) and the father showed one allele (homozygous) but for a different size allele. Patient EE shows only one allele from the mother and no allele from the father, thus a paternal deletion of the MN1 locus.
