In more than 98% of cases, the disease is associated with a G to A or G to C substitution at nucleotide position 1138 (p.G380R) of the fibroblast growth factor receptor 3 (FGFR3) gene. We have developed a sensitive single tube tetra-primer PCR assay to detect both the c.1138G\u003eA and c.1138G\u003eC mutations and can successfully distinguish DNA samples that are homozygous and heterozygous for the c.1138G\u003eA mutation. Titration studies showed that the assay could reliably detect one copy of the mutant allele in a mix of 100 wild-type alleles.
