Diagnosis of Laron syndrome using monoplex-polymerase chain reaction technology with a whole-genome amplification template: A case report

Figure 2 Electrophoresis of the monoplex polymerase chain reaction assay to determine the growth hormone receptor mutational status in the fetus of the pregnant mother. Amniocytes were extracted and were analyzed in triplicate by generating genomic DNA using the same procedure for embryos. 56009-LA-1 to -3 are the 3 independent analyses of the amniocytes. L1 (paternal: heterozygous for del5-6), L2 (affected child: homozygous for del5-6), L3 (maternal: heterozygous for del5-6), masculine (positive control for a homozygous male normal), (-) is the water control and the molecular weight marker. Results showed the presence of at least one copy of exon 5 of the growth hormone receptor gene; therefore, it can be concluded that the fetus will not present with Laron Syndrome but be a carrier (heterozygote) of Laron syndrome. GHR: Growth hormone receptor.
