Alaskan Malamute
23 Alaskan Malamutes in the atlas. Every number on this page has a source.
23 Alaskan Malamutes 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 Alaskan Malamute clusters consistently as Alaskan Malamute (100% of the 23 dogs here). At the trait loci, STC2 runs lower than average (22% here vs 74%); HMGA2 runs higher than the atlas average (87% here vs 56%). Dogs here sit in a relatively sparse region of the atlas, fewer close neighbors than typical.
High breed predictability score (1.73), individual dogs of this breed reliably cluster together genetically. Only 23 dogs of this breed in the atlas, modestly sampled.
Closest genetic neighbors in the atlas: Siberian Husky, village dog Us Alaska, Greenland Sledge Dog, Samoyed, and Chinook.

What does the genome say about how a Alaskan Malamute looks?
Alaskan Malamutes 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 sits at 74% for the small-body allele. IGF1 is the gene that sets dog body size from Chihuahua to Great Dane. Intermediate frequencies typically keep a breed in the mid-sized range rather than tipping toward the larger working forms.
HMGA2 is near-fixed at 87%, reinforcing the breed's size signal through a second locus on chromosome 10.
SMAD2 is near-fixed at 89%, a chromosome-7 height locus differentiating small from giant breeds.
LCORL sits at 85% at the NCAPG/LCORL height locus on chromosome 3.
STC2 is at 22%, leaving the growth-axis signal to other loci.
ADAMTS17 sits at 40%. ADAMTS17 is a body-size locus also linked to lens disorders.
Leg length
The FGF4 retrogene on chromosome 18 sits at 65%. 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 is near-fixed at 94%, the chondrodystrophic variant associated with intervertebral disc disease risk in breeds that carry it.
Coat type, length, and color
RSPO2 sits at 65% 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 is at 87% for the long-coat variant, which is why the breed's coat sits where it does on the long end of the dog coat-length spectrum.
KRT71 is near-fixed at 98% 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 94% at the representative SNP. MC1R controls the switch between red-to-gold and black-to-brown pigment, with the e/e homozygous genotype producing the gold-to-red spectrum by blocking eumelanin (black and brown pigment).
Ears
MSRB3 is at 96% for the drop-ear allele, the genetic basis of the breed's signature dropped ear set.
Skull shape
BMP3 sits at 80%, contributing to the breed's moderate, mesaticephalic head shape rather than the extreme brachycephalic form.
SMOC2 sits at 76%, contributing to the breed's moderate head shape.
What genetic diseases do Alaskan Malamutes carry?
From a panel of 250 Mendelian-disease variants screened in 1,054,293 dogs (Donner et al. 2023), Alaskan Malamutes carry 7 of them at observable frequency. Carrier frequency is not clinical risk. Most recessive variants require two copies for disease expression; many dominant variants show incomplete penetrance. Read this as a population fingerprint of what's in the gene pool, not a per-dog prediction.
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.
