chr12:34,964,869 in FGF4_retrogene_CFA12
Representative variant at the FGF4_retrogene_CFA12 leg length locus on CanFam4 (UU_Cfam_GSD_1.0). Alleles T/C. chondrodystrophy insertion site; not annotated as gene Per-breed allele frequencies are on the FGF4_retrogene_CFA12 gene page. Predicted disease relevance at the per-dog level is UNPROVEN; this variant tags a morphology locus, not a clinical phenotype.
