## TL;DR

A rare SARS-CoV-2 subvariant called LF.7.3 was discovered in Morocco and is part of the Omicron lineage.

## Contribution

The study reports the complete genome sequence of the previously undocumented SARS-CoV-2 subvariant LF.7.3 from Morocco.

## Key findings

- The subvariant LF.7.3 is a descendant of the JN.1 variant within the Omicron lineage.
- Genomic analysis confirms the classification of these strains as belonging to the LF.7.3 sublineage.

## Abstract

We report the coding-complete genome sequence of a rare severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) subvariant (LF.7.3) identified in Morocco. Genomic analysis indicates that these strains belong to the LF.7.3 sublineage, a descendant of the JN.1 variant within the Omicron lineage.
