Dog (Canis lupus familiaris) IGL locus on chromosome 26

The dog (Canis lupus familiaris) IGL locus is on chromosome 26. The orientation of the locus is forward (FWD).
The dog (Canis lupus familiaris) IGL locus spans 2583 kilobases (kb), from 10 kb upstream of the most 5' gene in the locus, IGLV1-162 (F), to 10 kb downstream of the most 3' gene in the locus, IGLC9 (F). The Locus representation encompasses 2800 kb including the 3' borne RSPH14.
The dog (Canis lupus familiaris) IGL locus consists of 261 IGLV genes belonging to 7 IGLV subgroups, 9 IGLJ genes belonging to 9 IGLJ sets, and 9 IGLC genes [1].
The IGLV genes span 2523 kilobases (kb), the IGL J-C-CLUSTER genes span 46 kilobases (kb).
The IGLJ and IGLC genes are localized in one J-C-CLUSTER that includes 9 IGLJ (functional) and 9 IGLC (functional).

RSPH14 (3' borne) has been identified 116 kb downstream of IGLC9, the most 3' gene in the locus.
