chromosome
chromosome on which an entity is localized

Description	the chromosome on which an entity is localized
Represents	chromosome (Q37748)
Data type	Item
Domain	According to this template: any item that can be localized to a set of genomic coordinates, e.g. a gene (Q7187), sequence variant (Q15304597), etc According to statements in the property: gene (Q7187), sequence variant (Q15304597), noncoding DNA (Q1458444) or chromosome abnormality (Q744962) When possible, data should only be stored as statements
Allowed values	any type of chromosome (Q37748) (see latest list), e.g. human chromosome 1 (Q430258), mouse chromosome 1 (Q14864323) (note: this should be moved to the property statements)
Example	RELN (Q414043) → human chromosome 7 (Q657319) rs267601217 (Q15304616) → human chromosome 7 (Q657319) GUF1 (Q14331135) → mouse chromosome 5 (Q15304656)

Value type “chromosome (Q37748)”: This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value chromosome (Q37748) (or a subclass thereof). (Help)

Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303).

Type “gene (Q7187), sequence variant (Q15304597), noncoding DNA (Q1458444), chromosome abnormality (Q744962)”: item must contain property “instance of (P31), subclass of (P279)” with classes “gene (Q7187), sequence variant (Q15304597), noncoding DNA (Q1458444), chromosome abnormality (Q744962)” or their subclasses (defined using subclass of (P279)).

remove allowed type non-coding RNA

I'm very sorry but RNA in general has no direct assocation with a chromosome. It may have an association with a gene or pseudogene. Mixing pseudogenes with RNA in one object is simply laziness and will hurt people or AIs in later searches. --SCIdude (talk) 07:29, 20 August 2019 (UTC) Ok, there may be a need for those cases where the DNA is intergenic, so I'll add the class noncoding DNA. So every genic noncoding RNA/intergenic RNA needs an pseudogene/noncoding DNA association for specifying the chromosome. --SCIdude (talk) 07:42, 20 August 2019 (UTC)

@SCIdude: I agree with you on principle, but this currently creates constraint violations in all microRNA articles such as hsa-mir-6085 (Q27591293), so we should probably remove the P1057 property from these and ensure they all have encoded by (P702) ? --Hannes Röst (talk) 18:01, 8 October 2020 (UTC)

Exactly, there are 4,558 such items (microRNA and mature microRNA). Note there are multiple issues like strand orientation, genomic start/end (should be both on gene), and the genes having P31+P279-->non-coding RNA. Of course, this is on my list but not at the top. --SCIdude (talk) 06:49, 9 October 2020 (UTC)
