Genetic Alterations
ENU-induced A to T transversion at base pair 66,859,821 (v38) on chromosome 18, or base pair 667 in the GenBank genomic region NC_000084 for the Mc4r gene. The mutation corresponds to residue 667 in the mRNA sequence NM_016977 within exon 1 of 1 total exons. The mutation results in an asparagine (N) to tyrosine (Y) substitution at position 74 (T74Y) in the MC4R protein.

Strain Description

Phenotype

Homozygous: Mice exhibited increased body weights compared to wild-type mice.

Heterozygous: Mice showed increased body weights compared to wild-type mice. Phenotype is intermediate between wild-type and homozygous mice.

Mammalian Phenotype Terms

  • growth/size/body
Strain Development
Original mutant was a C57BL/6J G3 ENU-induced mutant; all subsequent crosses to maintain strain were on C57BL/6J background only.
Suggested Control Mice
Wild-type littermates or C57BL/6J mice
