Species-specific symbol: tva
Species-specific description: As in many other cases of single-locus resistance, resistance to type A avian leukosis viruses is due to the lack of a functional receptor for the viruses.
Inheritance: Resistance to the A subgroup of avian sarcoma and leukosis viruses is a single-locus trait, with susceptibility being dominant and resistance recessive (Crittenden et al. 1967), who named the locus "tumour virus a" (tva).
Mapping: Bates et al. (1998) reported that the tva gene maps to within 5 cM of the receptor gene identified by Young et al. (1993), which (given the limited power of the linkage analysis) was strong evidence that the two genes are one in the same.
Molecular basis: The tva gene (i.e. the gene encoding the receptor for subgroup A viruses) was isolated, cloned and partially sequenced by Young et al. (1993), who performed two rounds of transfection with chicken genomic DNA (first into a monkey cell line and then into a mouse cell line) and subsequent selection for clones that are susceptible to subgroup A virus (and hence must be expressing the receptor for subgroup A viruses).
Elleder et al. (2004) fully sequenced this gene, and reported that two "different defects were identified in cDNAs cloned from two different ASLV(A)-resistant inbred chickens, line C and line 7(2). Line C tva(r) contains a single base pair substitution, resulting in a cysteine-to-tryptophan change in the LDLR-like region of Tva. This mutation [called allele tva^1] drastically reduces the binding affinity of Tva(R) for the ASLV(A) envelope glycoproteins. Line 7(2) tva(r2) contains a 4-bp insertion in exon 1 that causes a change in the reading frame, which blocks expression of the Tva receptor." This allele is called tva^r2.
Reinišová et al. (2012) identified two more resistance alleles at this locus, both disrupting splicing: tva^r3 is a 10bp deletion in intron 1 that includes a critical nucleotide of the deduced branch-point signal; tva^r4 is a 5bp deletion which also destroys the branch point signal.
Chen et al. (2015) identified two more resistance alleles, namely tva^r5 ("a [10bp] deletion of the sequence CGCTCACCCC (nucleotides 502 to 511)") and tva^r6 ("a [15bp] deletion of the sequence CGCTCACCCCGCCCC (nucleotides 502 to 516)").

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
