Malvina

Domestic Shorthair, registered Siberian on appearance · line: Malvina / Barnaul · the source records no eye colour · Published line, tested against the known variants and carrying none

Genealogy trace, one printable page carrying the proposed code

Under the variant field this directory proposes, this cat would read DBE 161 x5p. A carrier of a variant with no published allele, on a line this proposal gives a suffix to. The proposal is set out in full here, and no registry issues this field today: it is computed from the record at each build and is not part of any registration.

How this cat is connected to the trait

No recorded parent link joins this cat to a founder or to a tested animal. What the record rests on instead is the line recorded on it, Malvina / Barnaul, which is a source's attribution and not a descent this register can walk; and no recorded parent at all, which is a gap in the sources and not a statement that the cat had none.

No parent is recorded for this cat in the register, so no genealogy can be drawn. That is a gap in the sources, not a statement that the cat had none. Any offspring the register holds are listed below.

What the pedigree implies

Obligate carrier by pedigree. Malvina's blue-eyed boy, unnamed in the source, Slavicat X Tra Special, by 2 different mates

This is computed from the recorded parentage each time this site is built and is not typed into the register. It is a deduction from the trait being dominant, not a statement by any source, and it is not the same thing as the record's own status field. Only a laboratory settles it for an individual. The full list is on latent lines.

What is flagged

1. MALVINA. The breeder of the Meowrigi cattery gives her own account of this animal, relayed to this survey on 2 September 2026: She is the foundation of that line and she was found in Kazakhstan. The register holds her as found in Russia, at Barnaul in the Altai region, in 2015, and the researcher's 2026 presentation slide also calls this a line from Russia. The two countries are not reconciled here and both readings are kept: a found cat has no paperwork to settle it, and the Altai region borders Kazakhstan. Separately, the breed is open. This register holds her as a Siberian with a Siberian code, while the researcher's slide describes the line as a domestic shorthair line introduced into the Siberian breed, which would make the Siberian what she was bred into rather than what she was. That is the same shape of error corrected on the Marusya founder and it is recorded here rather than acted on. How the compiler reads the country disagreement: that the sources are probably not disagreeing about geography at all, but using Russia loosely for the whole post-Soviet region, so that a cat found on the Kazakh side of the Altai is written down as Russian. That reading is recorded and not adopted, and it is worth carrying beyond this animal, because several of this register's founding lines come from exactly that border country. S_RANO_228 she was mated to the Aktau founder and this register holds none of the kittens. The Meowrigi chart records two matings of Caspian Black Hole, the Aktau founder, to this animal, and the compiler was told on 2 September 2026 that the breeder who found her holds the offspring. Such a kitten would stand below the Barnaul founder on the dam's side and the Aktau founder on the sire's, which is the only mating of two separate dominant blue eye founders this survey has found. Neither determinant is identified and no test exists for either, so nothing is claimed about what those animals carry. The sire was deaf. Their pedigrees are the single most valuable thing outstanding on this line. The chain below her is repaired, 2 SEPTEMBER 2026. Her blue-eyed boy is now entered as a record of his own, where this register had wrongly put Raimonda Slavicat, and the descent to Velvet now runs through four names as the breeder describes it rather than three. S_BARNAUL_231 the breeder's own account of the find, 2 September 2026, answers every open question on this record. She is not a pedigree Siberian. She was found, and the breeder registered her as a Siberian because she looks like one, at a cattery that breeds Siberians. That is a registration made on appearance and not a descent, and it is why this survey's own records and Professor Abitbol's 2026 slide, which calls the line a domestic shorthair line introduced into the Siberian breed, were never really in conflict. The breed field is corrected to domestic shorthair and the Siberian registration is recorded here as what it is. She was already pregnant when she was found, by a tom cat, and that disposes of the date difficulty this register raised: a cat found in 2015 can have a kitten born early in 2015 if she arrived carrying it, so no earlier find and no impossibility need be supposed. The Tom is the black and white domestic shorthair this register already holds, unnamed, and he was never in anyone's hands. There were further kittens of that litter and this register holds only one of them, the blue-eyed boy who was crossed with Raimonda; the rest are a documented gap. S_BARNAUL_231 | seven DBE cats of this line were genotyped and the line is excluded from both new variants. Abitbol M, Eisele T and Lipovenko E, 'Additional PAX3 Variants for Dominant Blue Eyes in Cats', Animal Genetics 2026;57:e70199, Table 1 gives 'Malvina, 7' with four tested for DBE-NAD and all four wild-type, and four tested for DBE-MARU and all four C/C, which is wild-type. This is the first laboratory result this register has held for the Barnaul line and it is an exclusion, not an identification. The determinant of this line remains unpublished. S_PAX3_2026_235

A flag is not an error. It marks a place where two sources say different things, or where an attribution cannot be made on the evidence held.

The description held

tortoiseshell and white semi-longhair, registered SIB f 03 61. Found in 2015, and the registered pedigree carries that forward: all fourteen ancestor positions above her read Foundation, so the origin of the variant is unrecoverable behind her. Code 61 records blue eyes and states no cause. It recurs on at least nine of her charted descendants and on two of them in the pedigree database homozygosity in this line is stated to be lethal. Professor Marie abitbol, who identified DBE-ALT and DBE-CEL, states in her 2026 World Cat Federation presentation, on the slide headed 'Malvina line', that this is a dominant blue eye line from Russia, that it was introduced into the Siberian breed, that homozygosity is lethal, that there is no data on deafness, and that the search for the variant is ongoing. This is the researcher's statement and not this survey's finding: the presentation gives the conclusion without the underlying counts, so no number of lost kittens is claimed here. It is recorded against every animal of the line because a breeder looks up an animal and not a line. What it means in practice: mating two carriers of this determinant together is expected to lose the quarter of the litter that inherits two copies, and because those kittens do not survive to be counted, a breeder doing it may see only small litters and conclude nothing is wrong. It is a different and worse harm from the compound heterozygote this register documents elsewhere, which is white and deaf and which lives. The determinant of this line remains unidentified and this note does not attribute one. S_LETHAL_206

Note

The code and the description do not use the same words for this coat. Both are recorded and neither is reconciled to the other.

This directory is a working aid compiled from published charts, registry documents and breeder statements. It is not a register and it has no standing of any kind. The grade attaches to the animal, not to the line: a cat whose ancestor was genotyped is line-traced, not genotyped.
