Celeste line · DBE-CEL · line: Celeste (Chatterie d'Aerlin) · both eyes blue · Genotyped

Under the variant field this directory proposes, this cat would read DBE 162p. The variant is attributed to this animal from the record rather than from a result on it. 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

1. Narval
2. Muscari of Aerlin, the sire of Narval
3. Lazuli, the sire of Muscari of Aerlin. genotyped DBE-CEL; a founder of this survey

That is 2 recorded parent links, and the animal at the end of it has a laboratory result, so what this cat could carry is not a guess about a line but a consequence of a test on a relative. Every step is a parent recorded in this register from a document; none of them is an assumption. The full genealogy is drawn below, and the sources for each animal are on its own page.

The variant available to this cat

DBE-CEL, NOT ESTABLISHED FOR THIS ANIMAL. A DNA GENOTYPE SITS 2 GENERATIONS ABOVE THIS CAT. Lazuli is genotyped DBE-CEL. That does not settle what this cat carries, because a heterozygote passes the variant to half its offspring and the generations between are not tested. IT NAMES THE VARIANT AVAILABLE TO THIS ANIMAL AND THE ONE TO TEST FOR.

1. ROXI. BREEDING RECOMMENDATIONS THE PAGE ATTRIBUTES TO PROFESSOR MARIE ABITBOL OF THE VETAGRO RESEARCH LABORATORY. THE RESEARCHER AND THE SUBJECT ARE REAL AND THIS REGISTER ALREADY HOLDS HER WORK: Abitbol and others 2024, 'Different Founding Effects Underlie Dominant Blue Eyes in the Domestic Cat', Animals 14(13):1845; Abitbol and others 2024, 'A PAX3 insertion in the Celestial breed and certain feline breeding lines with dominant blue eyes', Animal Genetics 55; Abitbol and others 2024, 'PAX3 haploinsufficiency in Maine Coon cats with dominant blue eyes and hearing loss resembling the human Waardenburg syndrome', G3; and Abitbol and others 2025, 'Dominant blue eyes in Maine Coon cats: new PAX3 variant and updated phenotypic data', Animal Genetics. BUT THE LIST OF RECOMMENDATIONS BELOW IS THE BREEDER'S RENDERING OF THEM AND THIS REGISTER HAS NOT CHECKED IT AGAINST THOSE PAPERS. A real researcher being correctly named does not make a lay summary of her advice accurate. RECORDED AS THE BREEDER STATES IT, ATTRIBUTED AS THE BREEDER ATTRIBUTES IT, AND NOT ADOPTED. WHERE THIS REGISTER NEEDS THE SCIENCE IT CITES THE PAPERS DIRECTLY. THE LIST: do not breed DBE bloodlines with colourpoint or colourpoint carriers; with cats that have white, meaning bicolour, harlequin or van; with pure white cats; with cats born from DBE marriages that are born LATENT with orange eyes; or with recessive odd eyed. AND: 'Mixing, accidentally or not, a dominant cat to another dominant cat EVEN IF LATENT, can cause severe health issues in the first or future generations and should never be done' | THE DANGERS NAMED: 'Deafness (Altai, Topaz), CRANIAL MALFORMATIONS (Ojos Azules, a breed abandoned by the LOOF and TICA in 2004 because of issues). Other things commonly seen in dominant odd eyed is a KINKED TAIL or NOSE SHAPES THAT ARE STRANGE, of form and small or not equal nostrils.' And: 'DOMINANT TO DOMINANT ALSO SEEMS TO PRODUCE KITTENS WITH A LARGE AMOUNT OF WHITE EVEN IF THE PARENTS ARE SOLID' | THAT LAST OBSERVATION BEARS DIRECTLY ON MIYUKI OF AERLIN. He is out of Kaena and Lazuli, both of dominant lines, HIS BREEDER CALLS HIM HOMOZYGOUS, and he is SOLID WHITE AND DEAF where both parents carry only a chin patch. THE PAGE PREDICTS EXACTLY THAT OUTCOME FROM EXACTLY THAT MATING, and it predicts it as a harm | THE REGISTER RECORDS THIS AS A BREEDER'S STATEMENT OF PRACTICE AND AS A HEALTH CLAIM ATTRIBUTED TO A NAMED RESEARCHER. It does not endorse it, it has not verified the attribution, and it makes no recommendation about breeding
2. ROXI. Line and variant. The line Blue Eyed Maine Coons (Markiss) holds more than one variant across its records (DBE-ALT, DBE-CEL).
3. THE UNNAMED FEMALE DRAWN AS '??'. Unnamed, AND EXPECTED TO STAY THAT WAY. The charts draw her as '??' and give her nothing else: no name, no breed, no colour, no code and no eye. She is the dam of the one DNA-genotyped DBE-CEL animal in this register and every position above her is empty. THE HOLDER OF THIS MATERIAL STATED ON 19 AUGUST 2026 THAT ONE PARENT OF LAZULI WILL ALWAYS BE UNKNOWN. She is therefore not a gap awaiting a document and is not carried on any list of pedigrees to obtain. SHE IS THE ANIMAL WHOSE ABSENCE FROM THE RECORD THIS SURVEY IS ABOUT, and the absence is now a settled fact about the record rather than an outstanding question
4. LAZULI. BREEDING RECOMMENDATIONS THE PAGE ATTRIBUTES TO PROFESSOR MARIE ABITBOL OF THE VETAGRO RESEARCH LABORATORY.

5. IGRITTE. Segregation. A LITTER OF SIX, TWO SHOWING AND FOUR NOT, WHICH IS WHAT ONE DOMINANT ALLELE IN ONE PARENT PREDICTS. She is a cinnamon tortie British Shorthair drawn with no eye icon and carrying no variant label. Her mate Lazuli is DNA genotyped DBE-CEL. Two of their six are drawn blue or odd and four are bracketed as non-blue-eyed. THE RATIO IS NOT EVIDENCE ON ITS OWN at this size, and it is recorded because it could not be read off this register at all while the four stood as a single row
6. MUSCARI OF AERLIN. Cattery. THE AERLIN IS THE ONLY PREFIX IN THIS REGISTER HOLDING TWO VARIANTS, computed 18 August 2026 across 308 prefixes, of which 26 hold a named variant at all. Its seven records arrive in two bodies of material that share no cat: three on the Celeste chart out of Lazuli, carrying DBE-CEL, and four on genealogy C13, the Nanotigr line, of which Plumette d'Aerlin and Urist d'Aerlin carry DBE-ALT. THE CHART THE SECOND GROUP STANDS ON ALSO HOLDS ELEVEN ANIMALS WITH A LABORATORY RESULT, all DBE-ALT, AND NOT ONE OF THEM IS AN AERLIN CAT. What is recorded here is two variant attributions under one prefix and nothing further; IT IS NOT A LINK BETWEEN THE AERLIN AND THE IGOR LINES. NO PEDIGREE JOINS THE TWO GROUPS: searched through recorded parentage, no path runs from any Aerlin cat to a DNA-genotyped DBE-ALT cat or to the Igor group, because three of the seven carry no parent at all. A CATTERY IS NOT AN ANIMAL and no variant is moved between the two groups on this ground. ONE CATTERY UNDER TWO SPELLINGS, CONFIRMED. The English-language Celeste chart writes 'of Aerlin' and the French Nanotigr chart writes 'd'Aerlin'. The survey read them as one cattery because the Celeste chart is headed Chatterie d'Aerlin, and the holder of both charts confirmed it on 18 August 2026

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.

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.
