A new qualifier was introduced in version 10.6 (October 2016) of the Feature table definitions to be supported from 15-OCT-2016: /recombination_class

The text below outlines the format and the present list of allowed controlled vocabulary. Please note that mappings to Sequence Ontology (SO) are given in brackets () but should not be used as part of the value format. Please see below for examples.

Qualifier: /recombination_class

Definition: a structured description of the classification of recombination hotspot region within a sequence

Value format: “TYPE”

Examples:

/recombination_class=”meiotic”

/recombination_class=”chromosome_breakpoint”

Comment: TYPE is a term taken from the INSDC controlled vocabulary for recombination classes:

meiotic (SO:0002155): A genomic region in which there is an exchange of genetic material as a result of the repair of meiosis-specific double strand breaks that occur during meiotic prophase

mitotic (SO:0002154): A genomic region where there is an exchange of genetic material with another genomic region, occurring in somatic cells.

non_allelic_homologous (SO:0002094): A genomic region at a non-allelic position where exchange of genetic material happens as a result of homologous recombination.

chromosome_breakpoint (SO:0001021): A chromosomal region that may sustain a double-strand break, resulting in a recombination event.

other: /recombination_class not included in any other term.

/recombination classes not yet in the INSDC /recombination_class controlled vocabulary can be annotated by entering /recombination_class=”other” with /note=”[brief explanation of novel /recombination_class]”;
