Horse (Equus caballus) IGH locus on chromosome 24

The orientation of the horse (Equus caballus) IGH locus on the chromosome 24 is reverse (REV).

Legend:
Colors are according to IMGT color menu for genes.
The boxes representing the genes are not to scale. Exons are not shown.
A double slash // indicates a gap in genome assembly. Distances in bp (base pair) or in kb (kilobase) associated with a double slash are taken into account in the length of the lines and included in the numbers displayed at the right end of the lines.
A dotted line ... indicates the distance in kb (kilobase) between the locus and its bornes (5' borne and the most 5' gene in the locus and/or 3' borne and the most 3' gene in the locus) on the top and bottom lines, respectively. These distances are not represented at scale and are not included in the numbers displayed at the right ends of these two lines.

IGH gene names are according to the IMGT nomenclature [1].
Single arrows show genes whose polarity is opposite to that of the D-J-C-CLUSTER comprising IGHD (D1 to D40)-IGHJ (J1 to J9)-IGHC (IGHM-IGHD-IGHG1-IGHG2-IGHG3-IGHG4-IGHG6-IGHG5-IGHE-IGHA).

There are several gaps in the locus, the follow ones are not represented: the gap between IGHV4-37D and IGHV1-41, the gap between IGHV4-42 and GHV1-41D and the one between IGHV4-37D and IGHV1-41.

The IGHG7 constant gene is not found in the EquCab3.0 assembly, there is a gap at this position (IMGT000040 accession number). However, IGHG7 is found in the accession numbers NW_019645282 and in AY445517 [2]
