Genotype E has only been detected in Italy and it contains two subtypes, E1 and E2 [ 10, 11].
These regions also contain five subtype-specific substitutions that are situated either between or within the epitope clusters.
Type C contained three subtypes, a to c, but subtype a included 15 of 21 isolates.
SAG5 gene is an important member of SAG family genes and contains five subtypes from SAG5A to SAG5E [ 16, 17].
Genotype A is highly heterogeneous, since it contains at least fifteen subtypes, A1 to A15 [ 9, 10, 12- 15], while genotype B is less complex and contains three subtypes, B1 to B3 [ 9, 16].
These subgroups have variations in their oligomerization, conformation, and some secondary structure elements, and most organisms possess multiple isoforms (for example, humans contain four Prx1 subtypes, one Prx5 subtype, and one Prx6 subtype, whereas Escherichia coli has one Prx1, one Tpx, and one PrxQ).
4 13 The primary goal of the current experiment was to explicitly map neural responses to HWLs that contain three different subtypes of imagery that are frequently used in tobacco control communications, including HWLs on cigarette packaging: graphic representation of physical consequences of smoking; personal suffering from smoking-related consequences and symbolic representations of risk.
Furthermore, the Trembler-J heminodes and nodes contain two unusual ion channel subtypes: Nav1.8 and Kv3.1b.
Subtypes E, F and F1 are human specific as are some members of SVA subtype D. The younger subtypes appear to contain two GC rich VNTRs as opposed to the one seen in the older subtypes.
Mixed tumours (n=16) contain two or more different histological subtypes, making it impossible to categorise these tumours into a specific subtype.
