Status: draft. Extension maintained by: Health Level Seven International (Clinical Genomics)

The material on this page will be removed in a future release. This content is deprecated and SHOULD NOT be used. Implementers are instead directed to the (Genomics Reporting Implementation Guide) for guidance. A variation that increases or decreases the copy number of a given region (SO:0001019). Values: amplification/deletion/LOH.

Comment:

Loss of heterozygosity (LOH) is a functional variant whereby the sequence alteration causes a loss of function of one allele of a gene (SO:0001786).

Context of Use: Use on Element ID Observation
