Key result
The GH1:c.457C allele was associated with lower marbling (effect -0.22 SD, P=0.0472) and slightly higher rump fat (effect 0.11 SD, P=0.0541) in Australian feedlot cattle.
Observational (n=1,027)
Yes

The GH1:c.457C allele in cattle is associated with differential fat deposition, specifically lower marbling and higher rump fat.

Barendse et al. (2006) reported an observational. GH1:c.457C>G mutation was evaluated on marbling (average effect of allele substitution -0.22 SD, p=0.0472). The GH1:c.457C allele was associated with lower marbling (effect -0.22 SD, P=0.0472) and slightly higher rump fat (effect 0.11 SD, P=0.0541) in Australian feedlot cattle.
