Human (Homo sapiens) IGH locus assembly HG01243.alt.pat.f1_v2 (Puerto rican)
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.
IGH locus of assembly HG01243.alt.pat.f1_v2 is detected in two different scaffolds: in scaffold JAHEOY010000121.1 (IMGT000173) from IGHV7-81 to IGHA1*01 and in scaffold JAHEOY010000024.1 (IMGT000174) (IGHGP to IGHA2).
SWITCH sequences are represented
by a filled circle upstream of the IGHC genes.
IGHV genes which correspond to insertion/deletion polymorphisms but are not yet precisely located are not shown.
The Human (Homo sapiens) IGHV genes
belong to 7 subgroups (Gene
tables: Human IGHV) which are part of three clans
(Figure IGHV clans).
One additional clan only contains one pseudogene. Clans comprise, respectively:
- clan I: IGHV1, IGHV5 and IGHV7 subgroup genes
- clan II: IGHV2, IGHV4 and IGHV6 subgroup genes and 22 pseudogenes IGHV(II)
- clan III: IGHV3 subgroup genes and 18 pseudogenes IGHV(III)
- clan IV: Pseudogene IGHV(IV)-44-1
