Sec. 22.
(a) Two (2)
locations on DNA that code for prion protein are particularly important for
scrapie susceptibility and for the purposes of this article will be referred to
as follows:
(1) Codon 136 that may code for
the amino acids alanine (A) or valine (V).
(2) Codon 171 that may code for the amino
acids arginine (R), glutamine (Q), histidine (H), or lysine (K).
For the purposes of this article, amino acids H, K, or any
amino acid other than R at codon 171 will be treated as equivalent to Q at
codon 171.
(b)
The abbreviations for amino acids alanine (A), valine (V), arginine (R),
glutamine (Q), histidine (H), and lysine (K) apply throughout this
article.
(c) The following
definitions of genetic types of sheep apply throughout this article:
(1) "RR sheep" means any sheep that has
tested RR at codon 171 on an official genotype test.
(2) "QR sheep" means any sheep that has
tested QR, KR, or HR at codon 171 on an official genotype test.
(3) "QQ sheep" means any sheep that has
tested QQ, QK, QH, HK, KK, or HH at codon 171 on an official genotype
test.
(4) "AV sheep" means any
sheep that has tested AV at codon 136 on an official genotype test.
(5) "VV sheep" means any sheep that has
tested VV at codon 136 on an official genotype test.
(6) "AA sheep" means any sheep that has
tested AA at codon 136 on an official genotype test.
(7) "AA QR sheep" means any sheep that has
tested QR, KR, or HR at codon 171 and AA at codon 136 on an official genotype
test.
(8) "AV QR sheep" means any
sheep that has tested QR, KR, or HR at codon 171 and AV at codon 136 on an
official genotype test.
(9) "AA QQ
sheep" means any sheep that has tested QQ, QK, QH, HK, KK, or HH at codon 171
and AA at codon 136 on an official genotype test.
(10) "AV QQ sheep" means any sheep that has
tested QQ, QK, QH, HK, KK, or HH at codon 171 and AV at codon 136 on an
official genotype test.
(11) "VV QQ
sheep" means any sheep that has tested QQ, QK, QH, HK, KK, or HH at codon 171
and VV at codon 136 on an official genotype test.
(d) The state veterinarian may require
confirmatory testing before designating any animal a particular genetic class
under subsection (c).
