The callipyge mutation enhances the expression of coregulated imprinted genes in cis without affecting their imprinting status.

Nature genetics - 1 Apr 2001

Abstract excerpt

The callipyge (CLPG) phenotype (from kappa(alpha)lambda(iota), "beautiful," and pi(iota)gamma(epsilon), "buttocks") described in sheep is an inherited muscular hypertrophy that is subject to an unusual parent-of-origin effect referred to as polar overdominance: only heterozygous individuals having inherited the CLPG mutation from their sire exhibit the muscular hypertrophy. The callipyge (clpg) locus was mapped...
