gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...

The human GPR gene is located at the same site as the human ''FFAR1, FFAR,'' and ''FFAR3'' genes, i.e., on the
long (i.e., "q") arm of
chromosome 19
Chromosome 19 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 19 spans more than 58.6 million base pairs, the building material of DNA. It is considered the most gene-rich chromosom ...

segmental duplication
Low copy repeats (LCRs), also known as segmental duplications (SDs), are highly homologous sequence elements within the eukaryotic genome.
Repeats
The repeats, or duplications, are typically 10–300 kb in length, and bear greater than 95% sequ ...

Free fatty acid receptor
The free fatty acid receptor is a G-protein coupled receptor which binds free fatty acids. There are four variants of the receptor, each encoded by a separate gene ( FFAR1, FFAR2, FFAR3, FFAR4). Preliminary findings suggest that FFAR2 and ...
