Allele Symbol: a

Allele Name	nonagouti
Allele Type	Spontaneous
Allele Synonym(s)
Gene Symbol and Name	a, nonagouti
Gene Synonym(s)
Strain of Origin	old mutant of the mouse fancy
Chromosome	2
General Note	Insertion of the LV30 retrotransposon without the beta4 retrovirus sequence does not cause the nonagouti phenotype. J:278039
Molecular Note	Characterization of this allele shows an insertion of DNA comprised of a 5.5kb virus-like element, VL30, into the first intron of the agouti gene. The VL30 element itself contains an additional 5.5 kb sequence, flanked by 526 bp of direct repeats (beta4 retroviral sequence). The host integration site is the same as for a^t-2Gso and A^w-38J and includes a duplication of four nucleotides of host DNA and a deletion of 2 bp from the end of each repeat. Northern analysis of mRNA from skin of homozygotes shows a smaller agouti message and levels 8 fold lower than found in wild-type.

Molecular Note	Pulsed-field gel electrophoresis revealed an altered restriction fragment size consistent with a deletion of 160-200kb.

Itpr3^tf

Allele Symbol: Itpr3^tf

Allele Name	tufted
Allele Type	Spontaneous
Allele Synonym(s)	tf
Gene Symbol and Name	Itpr3, inositol 1,4,5-triphosphate receptor 3
Gene Synonym(s)
Strain of Origin	BTBR
Chromosome	17
General Note	This allele was recovered from a Harwell testing stock carrying multiple recessive markers in an undefined background. (J:273)
Molecular Note	Complementation mapping was used to demonstrate that this spontaneous mutation was an allele of Itpr3. Sequencing revealed a 12 bp deletion in Exon23 (Chr17: 27238069, Build 38.1) which codes for amino acids 983-986. This mutation arose early in the history of the BTBR strain (in or soon after 1956) and is not found in 18 other strains (129P2/OlaHsd, 129S1/SvImJ, 129S5/SvEvBrd, A/J, AKR/J, BALB/cJ, C3H/HeJ, C57BL/6NJ, CAST/EiJ, CBA/J, DBA/2J, FVB/NJ, LP/J, NOD/ShiLtJ, NZO/HlLtJ, PWK/PhJ, SPRET/EiJ and WSB/EiJ)

Mammalian Phenotype Terms by Genotype

The following phenotype information is associated with a similar, but not exact match to this JAX^® Mice strain

Genotype: Itpr3^tf/Itpr3^tf
involves: BTBR

integument phenotype

sparse hair
- waves of hair loss and growth create a sparse hair appearance anterior to posterior, ventral and dorsal

abnormal hair cycle
- a wave of hair loss begins ventrally under the jaw and spreads posteriorly
- a normal wave of hair growth follows the initial loss pattern
- a few days after ventral hair loss a similar dorsal wave of hair loss begins at the face, not including whiskers

abnormal hair growth

abnormal coat/ hair morphology
- alternating waves of hair loss and growth are repeated throughout the life of the mouse
- detectable about 4 weeks of age

taste/olfaction phenotype

abnormal gustatory system physiology
- in a 96 h two-bottle choice tests, mice exhibit higher preference for calcium chloride and calcium lactate compared with NZW mice
- in a 48 h two-bottle choice test, mice exhibit higher preference for calcium chloride, calcium lactate, denatorium, quinine hydrochloride and caffeine compared with NZW mice
- in a 96 h two-bottle choice tests, mice exhibit lower preference for saccharin and citric acid compared with NZW mice
- Normal - however, mice exhibit normal response to capsaicin
- in a 48 h two-bottle choice test, mice exhibit lower preference for sodium chloride, inosine monophosphate, trisodium pyrophosphate, saccharin, sucrose and hydrochloride compared with NZW mice

behavior/neurological phenotype

low sweet preference
- in a 96 h two-bottle choice tests, mice exhibit lower preference for saccharin compared with NZW mice
- in a 48 h two-bottle choice test, mice exhibit lower preference for saccharin and sucrose compared with NZW mice

abnormal liquid preference
- in a 48 h two-bottle choice test, mice exhibit lower preference for sodium chloride, inosine monophosphate, trisodium pyrophosphate, saccharin, sucrose and hydrochloride compared with NZW mice
- in a 48 h two-bottle choice test, mice exhibit higher preference for calcium chloride, calcium lactate, denatorium, quinine hydrochloride and caffeine compared with NZW mice
- in a 96 h two-bottle choice tests, mice exhibit higher preference for calcium chloride and calcium lactate compared with NZW mice
- Normal - however, mice exhibit normal response to capsaicin
- in a 96 h two-bottle choice tests, mice exhibit lower preference for saccharin and citric acid compared with NZW mice

increased fluid intake
- compared with NZW mice

growth/size/body region phenotype

increased body weight
- male, but not female, mice exhibit a slight increase in body weight compared with NZW mice

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
