has_variant_part is_variant_part_of has_affected_feature A relation that holds between an instance of a geneetic variation and a genomic feature (typically a gene class) that is affected in its sequence or expression. This class to organizes all relations used to link genetic variation instances of any type to genomic feature classes they effect. For example, is_allele_of links a gene allele instance to its gene class (genes are represented as classes in our OWL model). Such links support phenotype propagation from alleles to genes for Monarch Initiative use cases. Use of these properties effectively puns gene class IRIs into owl:individuals in a given rdf datset. is_feature_affected_by
