https://raw.githubusercontent.com/EbiEga/ega-metadata-schema/main/schemas/EGA.experiment.json#/properties/targetedLoci/itemsNode to unambiguously identify loci [OGI:0000022]: the unique chromosomal location defining the position of an individual gene or DNA sequence. This node shall be used to precisely define: (1) the organism of said locus; (2) the gene and other genomic feature references in other accessions; (3) the genomic sequence per se, including its assembly and position. These details, in different combinations, shall allow identification of any genomic feature, such as SNPs (e.g. coordinates of a variant) or genes (e.g. PT53).

This property describes the material entity the sample consists in. That is, an individual living system, such as animal, plant, bacteria or virus, that is capable of replicating or reproducing, growth and maintenance in the right environment. An organism may be unicellular or, like humans, made up of many billions of cells divided into specialized tissues and organs. This node is of special interest in case the provenance of the sample is not human (e.g. microbiota taken from a donor). Unless stated otherwise, given the nature of the EGA, it is expected to be of human provenance.
