Lhasa Apso Cn
12 Lhasa Apso Cns in the atlas. Every number on this page has a source.
12 Lhasa Apso Cns in the Sniff Atlas. Population-genetic snapshot, Mendelian carrier frequencies from Donner 2023, and the data substrate's release version, sample sizes, and evidence tier on every claim.
In the atlas, the Lhasa Apso Cn clusters consistently as Lhasa Apso Cn (100% of the 12 dogs here). At the trait loci, MC1R runs lower than average (0% here vs 62%); MSRB3 runs lower than average (21% here vs 80%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.
High breed predictability score (4.61), individual dogs of this breed reliably cluster together genetically. Only 12 dogs of this breed in the atlas, modestly sampled.
Closest genetic neighbors in the atlas: Qingchuan Hound, Chinese Rural Dog, Chow Chow, Guangxi Hound, and Akita.

What does the genome say about how a Lhasa Apso Cn looks?
Lhasa Apso Cns look the way they do because of a small set of fixed and near-fixed morphology genes that, taken together, define the visible breed. Each translation below pairs the gene with the trait an owner actually sees, the breed's allele frequency at that locus, and a one-clause causal phrase.
Size and build
IGF1 is near-fixed at 100% for the small-body allele, which keeps the breed compact relative to its working-line ancestors.
HMGA2 sits at 67%. HMGA2 is a chromosome-10 size locus that acts together with IGF1, and intermediate frequencies reflect partial commitment to the dominant size variant.
SMAD2 sits at 67% at the chromosome-7 height locus.
LCORL sits at 79% at the NCAPG/LCORL height locus on chromosome 3.
STC2 sits at 67%.
ADAMTS17 sits at 58%. ADAMTS17 is a body-size locus also linked to lens disorders.
Leg length
The FGF4 retrogene on chromosome 18 sits at 33%. This is the leg-length variant. The intermediate frequency means some dogs in this breed carry the short-legged allele and some do not.
The FGF4 retrogene on chromosome 12 sits at 83%, the chondrodystrophic variant.
Coat type, length, and color
RSPO2 sits at 54% for the furnishings variant. Furnishings (the eyebrow-and-mustache pattern seen in Schnauzers and Wheaten Terriers) vary across the population at this intermediate frequency, and visible expression depends on the specific allele combination each dog carries.
FGF5 sits at 46% for the long-coat variant. Coat length is influenced by other loci as well, so intermediate FGF5 frequencies do not always correspond to intermediate visible coat lengths.
KRT71 is near-fixed at 92% for the wavy/curly variant. Coat curl phenotype varies across breeds at this fixation depending on modifier loci, and visible expression is not always curled even when the locus is fixed.
MC1R is at 0% at the representative SNP, leaving the breed in the black-to-brown coat range under the dominant E allele.
Ears
MSRB3 is at 21% for the drop-ear allele, keeping the breed's ears upright and prick.
Skull shape
BMP3 is at 100%, contributing to the breed's brachycephalic skull shape.
SMOC2 sits at 50%, contributing to the breed's moderate head shape.
Where every number on this page came from.
This page draws on three primary data sources. Carrier frequencies for the Mendelian section come from Donner et al. 2023 (CC-BY-4.0). We grade these data at evidence Limited because the cohort is a direct-to-consumer ascertainment, which biases toward owners who chose to test their dogs. The panel also uses tag-SNP proxies for some variants rather than direct causal-variant assays. Limited is a study-design grade, not a quality grade: the Donner cohort is the largest open canine-genotype dataset in existence and we are grateful for it. We rate the confounding MEDIUM.
Population-genetic dimensions (heterozygosity, intra-breed PCA distance, nearest neighbors, trait-locus frequencies) come from CanVAS (Brundage 2026), harmonized through the Sniff Atlas. The exact release date and verification commit are pinned at the bottom of the page so a researcher can trace a number back to a specific snapshot. The disease-gene-variant graph comes from OMIA (Online Mendelian Inheritance in Animals; Nicholas, Tammen, and the Sydney Informatics Hub at the Sydney School of Veterinary Science, The University of Sydney; retrieved April 2026, DOI 10.25910/2AMR-PV70).
What this page does not yet have. Inheritance modes and per-disease penetrance evidence from Donner 2023 are now in the structured data for every variant the panel covers. Mondo, OMIM, Ensembl, and HGNC cross-references on gene pages remain pending — they arrive in December 2026 alongside the imputed 9.67M-variant CanVAS dataset via the OMIA SQL dump absorption. Until then, gene IDs carry NCBI Gene and OMIA phene URLs only; the wider human-homolog and disease-ontology cross-reference set fills in with that release.
