Figure 1: Mutation analysis for exon 2 of PVR gene. (A) A SSCP analysis of PCR products of PVR exon 2 in PPS patients; W refers to wild type and M as mutant. (B) Wild type alleles in control individual with GCG. (C) Mutant allele in PPS patients with GCG→ACG confirmation (highlighted refers to point of the mutation).
