Sumatran orangutan (Pongo abelii) IGH locus

The Sumatran orangutan (Pongo abelii) IGH locus orientation is reverse (REV).
The Sumatran orangutan (Pongo abelii) IGH locus spans 1561 kilobases (kb), from 10 kilobases (kb) upstream the most 5' gene in the locus, IGHV(II)-139 (P), to 10 kb upstream of the most 3' gene in the locus, IGHA2 (F). The Locus representation encompasses 1600 kilobases (kb).
The Sumatran orangutan (Pongo abelii) IGH locus consists of 192 genes : 139 IGHV genes belonging to 7 subgroups and 4 clans, 31 IGHD genes belonging to 7 sets, 9 IGHJ genes belonging to 9 sets and 13 IGHC genes .
The IGHV genes span 1100 kilobases (kb), the IGHD genes span 60 kilobases (kb), IGHJ genes span 20 kilobases (kb) and the IGHC gene spans 420 kilobases (kb).

TMEM121 (3' borne) has been identified 60 kb downstream of IGHA2, the most 3' gene in the locus.
