** Allelic polymorphism by insertion/deletion. The TRGV3P gene, a polymorphic gene by insertion, has been identified by Southern hybridization in a rare haplotype but has not been sequenced (Ghanem N. et al., Hum. Genet., 86, 450-456 (1991), PMID:1673112).
The most frequent haplotype comprises 14 TRGV genes (6 FUNCTIONAL + 3 ORF + 5 PSEUDOGENE) with V4 and V5 present, and V3P absent.
