Bornean orangutan (Pongo pygmaeus) IGH locus on chromosome 15

The Bornean orangutan (Pongo pygmaeus) IGH locus is on chromosome 15. The orientation of the locus is reverse (REV).
The Bornean orangutan (Pongo pygmaeus) IGH locus spans 1746 kilobases (kb), from 10 kilobases (kb) upstream the most 5' gene in the locus, IGHV(III)-145 (P), to 10 kb upstream of the most 3' gene in the locus, IGHA2 (F). The Locus representation encompasses 1780 kilobases (kb).
The Bornean orangutan (Pongo pygmaeus) IGH locus consists of 219 genes : 177 IGHV genes belonging to 7 subgroups and 4 clans, 31 IGHD genes belonging to 7 sets, 9 IGHJ genes belonging to 9 sets and 12 IGHC genes .
The IGHV genes span 1342 kilobases (kb), the IGHD genes span 60 kilobases (kb), IGHJ genes span 17 kilobases (kb) and the IGHC gene spans 327 kilobases (kb).

TMEM121 (3' borne) has been identified 62 kb downstream of IGHA2, the most 3' gene in the locus.
