Zephir Taiga Star
prefix Taiga Star · Siberian · line: Siberian, Altai or Barnaul unconfirmed · both eyes blue, and white or white spotting supplies the cause · Variant not known
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, Siberian, Altai or Barnaul unconfirmed, 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.

The description held
white, annotated 'Blue-eyed white'. As with his sire, dominant white removes the reading. Certified pedigree P18 gives two ordinary causes of the blue eye and no DBE ancestor: he is white by his sire V*Grand Sineglaziy Angel, SIB w 61, and his dam WCH Undina Lion's Heart is NEM n 21, a Neva Masquerade, which is colourpoint and blue-eyed of itself. Four complete generations, thirty ancestors of thirty possible, and every one is NEM or SIB of the Sineglaziy Angel, Lion's Heart, Sarji, Severnoe Sijanie and Zhemchug Nevy catteries 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

Source
C3 blue-eyed Siberian breeder-compiled genealogy, headed 'DBE siberians (Unconfirmed if Altai gene or Barnaul gene from Altai Region)'. Close-up tiles supplied to this survey on 13 August 2026. Certified pedigree P18, read from PawPeds 15 August 2026: CH (FIFe) Zephir Taiga Star, SIB w 61, RU/CZ, four complete generations, thirty ancestors of thirty possible, twenty-four unique, inbreeding 8.01 per cent. Excluded as a DBE attribution: the FIFe Siberian standard permits blue eyes with EMS codes w, 01 and 02, and requires them in the Neva Masquerade, so a white Siberian coded 61 is explained by the standard without reference to PAX3; and Abitbol M, 'CORIN and DBE variants in cats: what we know and what remains to be explored', World Cat Federation, 2026.

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.
