In patients with Albright hereditary osteodystrophy (AHO), heterozygous Gsα mutations only lead to obesity when present on the maternal allele. Similarly, mice with heterozygous germline Gsα mutations on the maternal allele develop severe obesity and insulin resistance with reduced energy expenditure relative t...
