Figure 1

GNRHR exon 1.1 bands on 2 percent agarose gel. All bands are clear and of proper size of 450 base pairs.

Figure 2

GNRHR 1.1 bands on polyacrylamide gel: Arrow shows the sample with double bands, further sequenced for detection of mutation. All other bands are well defined and single.

Figure 3

Mutated sequence of GNRHR exon 1.1 C-T change at nucleotide position 101 causing Ser34Phe change. Mutation is indicated by arrow.

Figure 4

Normal sequence of GNRHR exon 1.1. Arrow indicates the normal C position.
