MC4R V583


The DNA-test for the genetic variation in the gene identified melanocortin-4 receptor (MC4R) is associated with growth and leanness. The producer and breeder can decide if they wish to choose the fast growth form of the gene (298Asn, A-nucleotide variation) or the lean/efficient growth form of the gene (298Asp, G-nucleotide variation). Effects are 3 days less to market weight for animals homozygous for the growth allele compared to those homozygous for the lean allele. Pigs homozygous for the lean allele have 8 percent less backfat and have a high feed conversion rate.

Test specific information



The genetic factor is continuously present, and affects the meatquality.


Normally the result can be expected within 15 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received.

Location of disease or trait

Meat quality can be assessed in the meat.

Breed dependence

For this test samples from all breeds are accepted.

Sample type

For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, Tissue. Please contact PharmaDNA if you wish to submit other material as listed.


Meat quality is based on many genetic factors. For each factor, a separate test result will be returned.


Various genetic factors influencing meat quality are inherited in a dominant or recessive mode. Meat quality is influenced by a large number of genetic factors.

Severity of Disease

Genetic characteristics are not a disease.
