2. FIGURE 1
SSCP of the 251-bp fragment of exon 7 DRD2 demonstrated changing mobility in different controls and hyperprolactinemic patients. Subsequent sequencing of this fragment revealed polymorphism 1 at nucleotide 3420 and polymorphism 2 at nucleotide 3438 at the heterozygous (HTZ) or homozygous (HMZ) state or compound HTZ state for both polymorphisms.

3. FIGURE 2
Partial sequence of the antisense strand of the 251-bp fragment of exon 7 in a control, a homozygote for polymorphism 1 at nucleotide 3420, a homozygote for polymorphism 2 at nucleotide 3438, and a compound heterozygote for both polymorphism 1 and polymorphism 2. The G → A substitution for the antisense strand (corresponding C → T substitution for the sense strand) at nucleotides 3420 and 3438 does not change the amino acids histidine at position 313 and proline at position 319, respectively.
