(A and B) Pedigree structures (left) and patterns
of agarose gel electrophoresis on the RT-PCR analysis of
CADPS2 mRNA expressed in the blood of each individual
(right). (A) Male monozygotic autistic twins (TW1 [autistic
patient a5 shown in Figure 9A] and TW2
[autistic patient]) and their family members. A single major band (661 bp)
produced by normal alternative splicing is apparent in their father (F);
mother (M); older brother (B); and younger sister (S). On the other hand, an
additional, 381-bp band produced by exon 3–skipped alternative
splicing was expressed in both monozygotic autistic twins. (B)
The autistic patient (patient a4 shown in Figure 9A), who expressed only the exon
3–skipped shorter band, and the patient’s family
members. Similar to the family members in A, a single major
band of 661 bp is expressed in the father and mother. M, molecular weight
marker of the 100-bp ladder (from 200 bp at the bottom to 1000 bp at the
top).
