chr4:40,056,722 in STC2
Representative variant at the STC2 body size locus on CanFam4 (UU_Cfam_GSD_1.0). Alleles C/A. size locus chr4 Per-breed allele frequencies are on the STC2 gene page. Predicted disease relevance at the per-dog level is UNPROVEN; this variant tags a morphology locus, not a clinical phenotype.
